CodeForces 702 A Maximum Increase (贪心，高效算法)

题意：给定 n 个数，问你连续的最长的序列是几个。

析：从头扫一遍即可。

代码如下：

#include <cstdio>
#include <string>
#include <cstdlib>
#include <cmath>
#include <iostream>
#include <cstring>
#include <set>
#include <queue>
#include <algorithm>
#include <vector>
#include <map>
using namespace std ;
typedef long long LL;
typedef pair<int, int> P;
const int INF = 0x3f3f3f3f;
const double inf = 0x3f3f3f3f3f3f3f;
const double eps = 1e-8;
const int maxn = 1e5 + 5;
const int dr[] = {0, 0, -1, 1};
const int dc[] = {-1, 1, 0, 0};
int n, m;
inline bool is_in(int r, int c){
    return r >= 0 && r < n && c >= 0 && c < m;
}
int a[maxn];

int main(){
    cin >> n;
    for(int i = 1; i <= n; ++i)  scanf("%d", &a[i]);
    int ans = 1;
    int s = 0, e = 2;
    int cnt = 0;
    a[0] = 0;
    while(e <= n){
        cnt = 1;
        while(e <= n && a[e] > a[e-1]){  ++cnt;  ++e; }
        ans = max(ans, cnt);
        ++e;
    }

    cout << ans << endl;
    return 0;
}
