Getting Wrong Answer Why?

I am trying to solve decreasing string problem DECSTR Problem - CodeChef I have wrote the following code
int main(void)
int t,k,i;


		printf("%c", (97+k)-i);


return 0; 


I have complied and runned it successfully on codechef ide and shows correct o/p for testcases. However when i submit the code it shows wrong answer I dont really understand whats the error can someone please tell me whats lacking?

your code is not printing anything! check here

@rishabprsd7 thanks for replying i added getchar() still its not working check it doesn’t print anything dd0xZ5 - Online C Compiler & Debugging Tool -

@rjohari23 anything i can do to print data i tried myself but its not printing for your testcases but as per problems test cases its working now

Thats really strange… Dont know why ideone is not giving any output whereas in codeblocks output is printed.alt text

@rishabhprsd7 if k=100 then 97+k-i greater than the ASCII code of z that’s why u are getting those symbols

@sam_coder13 you should consider cases when k>=26.
