Test Status Code Input and Output
1   Pass
x = []; y = []; y_correct = 'ERROR'; assert(isequal(construct_string(x,y),y_correct))
2   Pass
x = [-1]; y = ['a']; y_correct = 'ERROR'; assert(isequal(construct_string(x,y),y_correct))
3   Fail
x = ['a']; y = [5]; y_correct = 'ERROR'; assert(isequal(construct_string(x,y),y_correct))

Error using repelem Replication factors must be numeric. Error in construct_string (line 7) y=repelem(letters,lengths); Error in Test3 (line 3) assert(isequal(construct_string(x,y),y_correct))
4   Pass
r = 10+randi(20); x = [r 1]; y = 'ab'; y_correct(1:r) = 'a'; y_correct(r+1) = 'b'; assert(isequal(construct_string(x,y),y_correct))
5   Pass
x = [5 4 3 2 1]; y = '.#4a5'; y_correct = '.....####444aa5'; assert(isequal(construct_string(x,y),y_correct))
6   Pass
x1 = [1 1 1 1 1 1]; y = 'banana'; assert(isequal(construct_string(x1,y),y))
