找了之前的比赛VP了一把,被自己的智商感动到了~~ 进入正题 C.Increase Subarray Sums 题意:对于给出的长度为n的序列和一个整数x,输出n+1个数表示让序列k( k = 1, 2, 3...n )个数加上x后序列的最大自段和 思路:处…
C. Increase Subarray Sums 传送门:Problem - 1644C - Codeforces 题目大意就是:给你一个序列,算出序列和为sum,求是否有连续区间和大于等于sum,有就输出NO,否则YES,并且连续区间不能是[1,n],也就是整个序列,我的思路就是构建两个DP数组,既然区间不能是1->n,那么一个dp从1->n-1,第二个从2->n,求dp...

Method 2: Optimized Subarray Enumeration We can optimize the first solution using the below technique. So let’s see the technique to how we can increase the performance of the above solution. If you know the sum of the subarray from index‘i’to index‘j’,then then the sum of the suba...
