<a href = "http://www.mathworks.com/help/matlab/characters-and-strings.html">String array</a> and cell array are two types of containers for storing pieces of data. In this problem, you will be given a cell array of character vectors. Your job is to convert the cell array to a string array, which stores the same pieces of text data.To begin with, let's assume that there are no missing type values in the input cell array.Example:<pre class="language-matlab">Input:
&gt;&gt; x = {'I','Love','MATLAB'}
x =
 1×3 cell array
 'I' 'Love' 'MATLAB'
</pre><pre class="language-matlab">Output:

&gt;&gt; [y{:}] = x{:}
y = 
 1×3 string array
 "I" "Love" "MATLAB"

<http://www.mathworks.com/help/matlab/characters-and-strings.html String array> and cell array are two types of containers for storing pieces of data. In this problem, you will be given a cell array of character vectors. Your job is to convert the cell array to a string array, which stores the same pieces of text data.

To begin with, let's assume that there are no missing type values in the input cell array.

Example:

Input:
  >> x = {'I','Love','MATLAB'}
  x =
    1×3 cell array
      'I'    'Love'    'MATLAB'

Output:
  >> y = strings(size(x));
  >> [y{:}] = x{:}
  y = 
    1×3 string array
      "I"    "Love"    "MATLAB"
