Can you solve this real interview question? Total Hamming Distance - The Hamming distance [https://en.wikipedia.org/wiki/Hamming_distance] between two integers is the number of positions at which the corresponding bits are different. Given an integer ar
The price sum of a given path is the sum of the prices of all nodes lying on that path. Additionally, you are given a 2D integer array trips, where trips[i] = [starti, endi] indicates that you start the ith trip from the node starti and travel to the node endi by any path you...

Fun one.. the punch line of this problem is quite common in Bit related problems on HackerRank - visualize it in your mind, and you will find: all bits on the same index among all numbers, will not involve other bits on other indices. So, we simply count number of 0s or 1s, on ...
Alice 是n个花园的园丁,她想通过种花,最大化她所有花园的总美丽值。 给你一个下标从0开始大小为n的整数数组flowers,其中flowers[i]是第i个花园里已经种的花的数目。已经种了的花不能移走。同时给你newFlowers,表示 Alice 额外可以种花的最大数目。同时给你的还有整数target,full和partial。
1010. 总持续时间可被 60 整除的歌曲 - 在歌曲列表中,第 i 首歌曲的持续时间为 time[i] 秒。 返回其总持续时间(以秒为单位)可被 60 整除的歌曲对的数量。形式上,我们希望下标数字 i 和 j 满足 i < j 且有 (time[i] + time[j]) % 60 == 0。 示例 1: 输入:time
