I am a beginner on codeforces so don't know how to tackle this issue. https://codeforces.com/contest/356/submission/122771867 is the link to my submission for problem https://codeforces.com/contest/356/problem/A.

This gives a runtime error on test case 11. The checker LOG gives the following message: "Exit code is -1073741819" along with the message "Probably, the solution is executed with error 'out of bounds' on the line 8". Please tell me how to rectify this issue.
