When the length of the string is exactly $$$100$$$,
fgets(s, MAX_LEN, stdin);reads only these $$$100$$$ characters and not the'\n'character after the string. Therefore, your code cannot judge the end of the string by checking whether it's'\n'.thank you! i get it now. i defined MAX_LEN as 101, but fgets reads MAX_LEN-1 which are given 100 chars but not the last entered '\n' and the condition never know when to break which causing the runtime error. the solution got accepted after i updated MAX_LEN as 102, where fgets reads till '\n'
