I have some problems with task 1181B. I have 2 main submissions. They are : https://mirror.codeforces.com/contest/1181/submission/55673412 and https://mirror.codeforces.com/contest/1181/submission/55673377. if you compare them, u will see that only difference between them string "x += s[i];" in 2 loops. But difference between memories of this 2 submissions is 524300 kb. Can someone say why it is?

Hello everyone! I am beginner and i hope you will help me. I was solving "Waffle Choppers" from Google Code Jam 2019 Round 1A and i got MLE but i don't understand why. I hope you will help me. My code : https://pastebin.com/uGFEEhQe And arrangements on some variables : 2 ≤ R ≤ 100. 2 ≤ C ≤ 100. 1 ≤ H < R. 1 ≤ V < C. Thanks a lot!
