#include<iostream> using namespace std; int main(){ int n,m,k=0; cin>>n>>m; while(n>=m){ n-=m; m+=1; k+=1; } cout<<k; return 0; }

每天i++，i++了几次就是几天

#include <iostream> using namespace std; int main() { int n,m; cin >> n >> m; int sum = 0; int day = 0; while(sum + m <= n ){ sum += m; day++; m++; } cout << day; return 0; }

#include"iostream" using namespace std; int main(){ int n,m,s=0; cin>>n>>m; while(n>=m){ n=n-m; m=m+1; s++; } cout<<s; return 0; }
