What is wrong in this code?

#1

I am gettting correct output on other IDE and online IDE of coding block, but getting wrong output on submission form IDE.

#2

hi @itismohiton this doesn’t account for cases like
90 9000 where expected answer is 909000 but this code will give answer as 900990

#3

What changes should i do in this code?

#4

@itismohiton you can do a comparison of (a+b) and (b+a) instead of a and b directly. (+ refers to concatenation of strings in C++)
