relatively recent addition to MATLAB, first having been available in R2016. Strings contrast with character arrays, and often allow you to work more naturally with textual data than character arrays do.\r\n\r\nStrings support some infix operators in MATLAB. In particular, you can concatenate strings by adding them; writing \"Hello \" + \"world\" yields \"Hello world\". On the other hand, scalar multiplication -- multiplying a string and a natural number -- is not possible: \"ho\" * 3 does not equal \"hohoho\", and instead produces an error message (in R2022b Update 3).\r\n\r\nSo let's remedy that! Your mission, should you choose to accept it, is to write a function that accepts as its inputs a string array in_str (of any size) and a scalar n, and that outputs a string array out_str (of the same size as in_str) such that out_str(k) is, for any k between 1 and numel(in_str), equal to in_str(k) repeated n times. You may assume that nothing funny will get passed to your function --- in particular, n will always be a non-negative integer.\r\n\r\nThe problem's easy to solve, but please try to find the most natural, the most elegant, the most MATLABian solution. Good luck, and have fun!\r\n\r\nP.S. Please don't cheat. I'll not attempt to detect cheating in the test suite, but please be a good sport.\r\n\r\nP.P.S.

In computing, numbers can be stored in a number of ways, but they all share the trait of being stored as a binary number. As such, the equals operator in MATLAB is checking the bits of one stored number against the bits of another stored number.

The strings will be given in the order the teams batted and will have the form \"TeamName r/w\" (where r is runs and w is wickets). If a team is all out, their score will be given as just \"TeamName r\".\r\nFor example, \"Pakistan 159/8\" and \"India 160/6\" means that Pakistan batted first and the result should be \"India won by 4 wickets\".

For example, the clue “??BID” had the answer RABID, with the accompanying word BRAID. The clue “??PREME” had the answer SUPREME, with the accompanying word PRESUME.\u003c/w:t\u003e\u003c/w:r\u003e\u003c/w:p\u003e\u003cw:p\u003e\u003cw:pPr\u003e\u003cw:pStyle w:val=\\\"text\\\"/\u003e\u003cw:jc w:val=\\\"left\\\"/\u003e\u003c/w:pPr\u003e\u003cw:r\u003e\u003cw:t\u003eIn a similar way, one can define two-bit primes: prime numbers whose first two digits can be shifted, as a unit, elsewhere in the number to form a new prime number. The first in the sequence is 113, with accompanying prime 311, followed by 131, with accompanying prime 113. Some two-bit primes can have multiple accompanying primes. For example, the two-bit prime 99611 has two accompanying primes: 69911 and 61991. Leading zeros are allowed: 1103 is a two-bit prime because 311 is also prime. \u003c/w:t\u003e\u003c/w:r\u003e\u003c/w:p\u003e\u003cw:p\u003e\u003cw:pPr\u003e\u003cw:pStyle w:val=\\\"text\\\"/\u003e\u003cw:jc w:val=\\\"left\\\"/\u003e\u003c/w:pPr\u003e\u003cw:r\u003e\u003cw:t\u003eRemember that the two-bit prime and its accompanying prime must differ. For example, the first two digits of 99991 can be moved one or two places to the right, but the resulting number (99991) is the same. Because 99199 is not prime, 99991 is not a two-bit prime. \u003c/w:t\u003e\u003c/w:r\u003e\u003c/w:p\u003e\u003cw:p\u003e\u003cw:pPr\u003e\u003cw:pStyle w:val=\\\"text\\\"/\u003e\u003cw:jc w:val=\\\"left\\\"/\u003e\u003c/w:pPr\u003e\u003cw:r\u003e\u003cw:t\u003eWrite a function to list the \u003c/w:t\u003e\u003c/w:r\u003e\u003cw:customXml w:element=\\\"equation\\\"\u003e\u003cw:customXmlPr\u003e\u003cw:attr w:name=\\\"displayStyle\\\" w:val=\\\"false\\\"/\u003e\u003cw:attr w:name=\\\"altTextString\\\" w:val=\\\"n\\\"/\u003e\u003c/w:customXmlPr\u003e\u003cw:r\u003e\u003cw:t\u003en\u003c/w:t\u003e\u003c/w:r\u003e\u003c/w:customXml\u003e\u003cw:r\u003e\u003cw:t\u003eth two-bit and all its accompanying primes. \u003c/w:t\u003e\u003c/w:r\u003e\u003c/w:p\u003e\u003c/w:body\u003e\u003c/w:document\u003e\",\"relationship\":null}],\"relationships\":[{\"relationshipType\":\"http://schemas.mathworks.com/matlab/code/2013/relationships/document\",\"target\":\"/matlab/document.xml\",\"relationshipId\":\"rId1\"}]}"},{"id":57829,"title":"Convert vector of strings to lower triangular matrix","description":"Given a non-empty vector vec of strings, please put its elements into the lower triangular half of a square matrix M column-wise.

relatively recent addition to MATLAB, first having been available in R2016. Strings contrast with character arrays, and often allow you to work more naturally with textual data than character arrays do.\r\n\r\nStrings support some infix operators in MATLAB. In particular, you can concatenate strings by adding them; writing \"Hello \" + \"world\" yields \"Hello world\". On the other hand, scalar multiplication -- multiplying a string and a natural number -- is not possible: \"ho\" * 3 does not equal \"hohoho\", and instead produces an error message (in R2022b Update 3).\r\n\r\nSo let's remedy that! Your mission, should you choose to accept it, is to write a function that accepts as its inputs a string array in_str (of any size) and a scalar n, and that outputs a string array out_str (of the same size as in_str) such that out_str(k) is, for any k between 1 and numel(in_str), equal to in_str(k) repeated n times. You may assume that nothing funny will get passed to your function --- in particular, n will always be a non-negative integer.\r\n\r\nThe problem's easy to solve, but please try to find the most natural, the most elegant, the most MATLABian solution. Good luck, and have fun!\r\n\r\nP.S. Please don't cheat. I'll not attempt to detect cheating in the test suite, but please be a good sport.\r\n\r\nP.P.S.

In computing, numbers can be stored in a number of ways, but they all share the trait of being stored as a binary number. As such, the equals operator in MATLAB is checking the bits of one stored number against the bits of another stored number.

The strings will be given in the order the teams batted and will have the form \"TeamName r/w\" (where r is runs and w is wickets). If a team is all out, their score will be given as just \"TeamName r\".\r\nFor example, \"Pakistan 159/8\" and \"India 160/6\" means that Pakistan batted first and the result should be \"India won by 4 wickets\".

For example, the clue “??BID” had the answer RABID, with the accompanying word BRAID. The clue “??PREME” had the answer SUPREME, with the accompanying word PRESUME.\u003c/w:t\u003e\u003c/w:r\u003e\u003c/w:p\u003e\u003cw:p\u003e\u003cw:pPr\u003e\u003cw:pStyle w:val=\\\"text\\\"/\u003e\u003cw:jc w:val=\\\"left\\\"/\u003e\u003c/w:pPr\u003e\u003cw:r\u003e\u003cw:t\u003eIn a similar way, one can define two-bit primes: prime numbers whose first two digits can be shifted, as a unit, elsewhere in the number to form a new prime number. The first in the sequence is 113, with accompanying prime 311, followed by 131, with accompanying prime 113. Some two-bit primes can have multiple accompanying primes. For example, the two-bit prime 99611 has two accompanying primes: 69911 and 61991. Leading zeros are allowed: 1103 is a two-bit prime because 311 is also prime. \u003c/w:t\u003e\u003c/w:r\u003e\u003c/w:p\u003e\u003cw:p\u003e\u003cw:pPr\u003e\u003cw:pStyle w:val=\\\"text\\\"/\u003e\u003cw:jc w:val=\\\"left\\\"/\u003e\u003c/w:pPr\u003e\u003cw:r\u003e\u003cw:t\u003eRemember that the two-bit prime and its accompanying prime must differ. For example, the first two digits of 99991 can be moved one or two places to the right, but the resulting number (99991) is the same. Because 99199 is not prime, 99991 is not a two-bit prime. \u003c/w:t\u003e\u003c/w:r\u003e\u003c/w:p\u003e\u003cw:p\u003e\u003cw:pPr\u003e\u003cw:pStyle w:val=\\\"text\\\"/\u003e\u003cw:jc w:val=\\\"left\\\"/\u003e\u003c/w:pPr\u003e\u003cw:r\u003e\u003cw:t\u003eWrite a function to list the \u003c/w:t\u003e\u003c/w:r\u003e\u003cw:customXml w:element=\\\"equation\\\"\u003e\u003cw:customXmlPr\u003e\u003cw:attr w:name=\\\"displayStyle\\\" w:val=\\\"false\\\"/\u003e\u003cw:attr w:name=\\\"altTextString\\\" w:val=\\\"n\\\"/\u003e\u003c/w:customXmlPr\u003e\u003cw:r\u003e\u003cw:t\u003en\u003c/w:t\u003e\u003c/w:r\u003e\u003c/w:customXml\u003e\u003cw:r\u003e\u003cw:t\u003eth two-bit and all its accompanying primes. \u003c/w:t\u003e\u003c/w:r\u003e\u003c/w:p\u003e\u003c/w:body\u003e\u003c/w:document\u003e\",\"relationship\":null}],\"relationships\":[{\"relationshipType\":\"http://schemas.mathworks.com/matlab/code/2013/relationships/document\",\"target\":\"/matlab/document.xml\",\"relationshipId\":\"rId1\"}]}"},{"id":57829,"title":"Convert vector of strings to lower triangular matrix","description":"Given a non-empty vector vec of strings, please put its elements into the lower triangular half of a square matrix M column-wise.
