CF11A Increasing Sequence入门题,就不解释了题解:算法复杂度为O(n)#include <iostream> #include <algorithm> using namespace std; int a[2001]; int main() { int n,b,ans; cin>>n>>b; for(int i=1;i<=n;i++) {cin>>a[i]; } for(int i=2;i<=n;i++)...
http://www.codeforces.com/contest/11/problem/A Description A sequence a0, a1, ..., at - 1 is called increasing if ai - 1 < ai for each i: 0 < i < t. You are given a sequence b0, b1, ..., bn - 1 and a positive integer d. In...
