Test Status Code Input and Output
1   Pass
%% x = 3276; y_correct = 5; assert(isequal(KaprekarSteps(x),y_correct))

2   Fail
%% x = 3; y_correct = 6; assert(isequal(KaprekarSteps(x),y_correct))

Error: Assertion failed.

3   Fail
%% x = 691; y_correct = 7; assert(isequal(KaprekarSteps(x),y_correct))

Error: Maximum recursion limit of 500 reached. Use set(0,'RecursionLimit',N) to change the limit. Be aware that exceeding your available stack space can crash MATLAB and/or your computer.
