A. Increasing Sequence 题目连接: 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…

Increasing Sequence CodeForces - 11A 很简单的贪心.由于不能减少元素,只能增加,过程只能是从左到右一个个看过去,看到一个小于等于左边的数的数就把它加到比左边大,并记录加的次数. 错误记录: 但是很容易错...以前错了4次..过几个月来再做还是不能1A... 比如下面这个有很明显错误的程序 #include<cstdio> int n,d,last,now,ans; int main() { int i; scanf("%d%d",&…

题意: 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 each move you may choose one element of the given sequence and add d to it. Wh…

Given an array, determine whether there are three elements A[i],A[j],A[k], such that A[i]<A[j]<A[k] & i<j<k. Analysis: It is a special case of the Longest Increasing Sequence problem. We can use the O(nlog(n)) algorithm, since we only need…

Given an unsorted array of integers, find the length of longest increasing subsequence. For example,Given [10, 9, 2, 5, 3, 7, 101, 18],The longest increasing subsequence is [2, 3, 7, 101], therefore the length is 4. Note that there may be more than o…

Given an integer array, your task is to find all the different possible increasing subsequences of the given array, and the length of an increasing subsequence should be at least 2 . Example: Input: [4, 6, 7, 7] Output: [[4, 6], [4, 7], [4, 6, 7], [4…
