## [Link to the problem on Hackerearth](https://www.hackerearth.com/practice/algorithms/string-algorithm/string-searching/practice-problems/algorithm/maximum-substring-9b97fc5f/description/) If we take the string as “apyzayz” , I think the output should be “yz” . But some solutions getting “a” as the output for this testcase, got an AC solution. When I ran @aryanc403 's solution (Screenshot below) against the provided custom input, it gave the answer as “a”. [Link to the solution](https://www.hackerearth.com/challenges/competitive/august-easy-201/algorithm/maximum-substring-9b97fc5f/submission/44993634/) ![Screenshot (847)](https://s3.amazonaws.com/discourseproduction/original/3X/c/b/cb8e294d4ae44b972555f313801ba01d717a52ec.png)

**Next ambiguity** I feel is that for the input as “xyzabcabcxyz”, the correct answer should be “xyz” as the question says “_print the one with the minimum index of the first occurrence._” But there are many solutions which are giving “abc” as the output and still got AC. [Link to one such solution](https://www.hackerearth.com/challenges/competitive/august-easy-201/algorithm/maximum-substring-9b97fc5f/submission/45001062/)  
@aryanc403 Please correct me if I am wrong.
