Is vec.resize(n, 0) take more memory than, vec.resize(n) and then intialize by loop???

I solved this problem [https://codeforces.net/problemset/problem/1335/F](https://codeforces.net/problemset/problem/1335/F) ↵
get memory limit exceed on test case  46 by this solution  [https://codeforces.net/contest/1335/submission/76658211](https://codeforces.net/contest/1335/submission/76658211) and get accepted by this solution [https://codeforces.net/contest/1335/submission/77233784](https://codeforces.net/contest/1335/submission/77233784). I only change the type to resize and initialize the vector;↵
