<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 = strings(size(x));
&gt;&gt; [y{:}] = x{:}
y = 
 1×3 string array
 "I" "Love" "MATLAB"
</pre>Note that the example shown above is not the best way to solve this problem.
