There are a number of spherical balloons spread in two-dimensional space. For each balloon, provided input is the start and end coordinates of the horizontal diameter. Since it's horizontal, y-coordinates don't matter and hence the x-coordinates of s…

Construct minimum number by reordering a given non-negative integer array. Arrange them such that they form the minimum number. Notice The result may be very large, so you need to return a string instead of an integer. Have you met this question in a…
Given an integer array (index from 0 to n-1, where n is the size of this array), and an query list. Each query has two integers [start, end]. For each query, calculate the minimum number between index start and end in the given array, return the resu…

In an array A containing only 0s and 1s, a K-bit flip consists of choosing a (contiguous) subarray of length K and simultaneously changing every 0 in the subarray to 1, and every 1 in the subarray to 0. Return the minimum number of K-bit flips requir…
Given a value V, if we want to make change for V cents, and we have infinite supply of each of C = { C1, C2, .. , Cm} valued coins, what is the minimum number of coins to make the change? Examples: Input: coins[] = {25, 10, 5}, V = 30 Output: Minimum…

805D - Minimum number of steps 思路:简单模拟,a每穿过后面一个b,b的个数+1,当这个a穿到最后,相当于把它后面的b的个数翻倍.每个a到达最后的步数相当于这个a与它后面已经到达最后的a之间的b的个数,只要从后面往前扫,记录b的个数,每遇到一个a,把b的个数加入答案,并且b的个数翻倍. 代码: #include<bits/stdc++.h> using namespace std; const int INF=0x3f3f3f3f; ; ; int main()…
