最大子串和
- 题意:
- 给出n个数,让你输出这n个数的最大连续子序列 的左端点和右端点和最大值
- 输入:
- 5
- -1 2 3 -4 9
- 输出:
- max= 10,L= 2,R= 5
- 代码:
#include <bits/stdc++.h> using namespace std; int main() { int m,l,r,start,maxx; int dp[100010]; scanf("%d",&m); for(int i = 1;i <= m;i++) scanf("%d",&dp[i]); l = r = start = 1; maxx = dp[1]; for(int i = 2;i <= m;i++) { if(dp[i-1] >= 0) dp[i] = dp[i-1] + dp[i]; else start = i; if(dp[i] > maxx){ maxx = dp[i]; l = start; r = i; } } cout<<"max= "<<maxx<<",L= "<<l<<",R= "<<r<<endl; return 0; }
