My code is below, but I cannot use the last line of code(less=string(worda)

function sortedarray=sortWords(array)

sortedarray={};

while ~isempty(array)

[m,pos]=findSmallest(array);

array(pos)=[];

sortedarray=[sortedarray m];

end

end

function [m, pos]=findSmallest(array)

m = array{1};

pos=1;

for i=2:length(array)

if isLessWord(array{i}, m)

m=array{i};

pos=i;

end

end

end

function less=isLessWord(wordA,wordB)

worda=lower(wordA);

wordb=lower(wordB);

less=string(worda)

end

Write a function sortWords (array) that does the following: 1. Takes as an input a cell array of strings consisting of letters only. (1 pts) 2. Returns a cell array with all the strings in alphabetical order. (5 pts) 3. The function should ignore whether letters are lower case or upper case. (2 pts) Test your function with the following: (e pts) >> sorted-sortWords ({"Hello, , , hell, , , abc, , , aa, , , a za , , , aab, , , AaBb , , , a, }) sorted- 'a' 'aa''aab' 'AaBb' 'abc' 'aza''hell' 'Hello Note: Your function may not contain any built-in MATLAB function(s) that deal with sorting or finding minimum values. If your function-does use these built-in functions, up to 8 points may be deducted from your total. Hint: Use the program sharkSort (vec) as a starting point and amend it so that it works for this programming assignment. For example your function could start as follows (fill in the blanks as necessary)
