Description
A simple yet tedious task occurs near the end of most Sudoku-solving algorithms, computerized or manual. The task is, given the row (or column or square) of a Sudoku puzzle with only a single number missing, fill in the missing number and return a completed row.
For more information regarding Sudoku, refer to the Wikipedia Entry for Sudoku.
The input will be in the form of a vector (row or column) or a 9x9 matrix and the output has to have the same dimensionality as the input. Blank entries are signified with the number 0. There will always be one and only one blank entry in the input.
Example
input = [ 1 2 3 4 0 6 7 8 9 ];
output = [ 1 2 3 4 5 6 7 8 9 ];
Problem description says the input can be a 9x9 matrix, but the test suite gives a 3x3 instead.
No 3x3 matrix in the description
3x3 for test
The second test case of matrix is not required..that never happens with sudoku. Only rows and columns should be inputs.
I've always wanted to create an algorithm to solve sudoku
neat & quick
