Given an integer array nums, return the sum of Hamming distances between all the pairs of the integers in nums.Example 1:Input: nums = [4,14,2] Output: 6 Explanation: In binary representation, the 4 is 0100, 14 is 1110, and 2 is 0010 (just showing the four bits relevant in this ...
The total of all the individual strengths of the wizards in the group. Returnthe sum of the total strengths of all contiguous groups of wizards. Since the answer may be very large, return it modulo109 + 7. A subarray is a contiguous non-empty sequence of elements within an array. Examp...

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...
2234. 花园的最大总美丽值 - 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
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
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 ...
