Leetcode: Subarray Sum Equals K\\\Binary Subarrays With Sum Problem Given an array of integers and an integer k, you need to find the total number of continuous subarrays whose sum equals to k. Example 1: Input: nums = [1,1,1], k = 2 Output: 2 Note: The length......
这题可以利用HashMap,把出现过的sum 当作key 存入, 把这个sum 出现过的次数 当作value 存入。 遍历nums array,一直更新sum,然后去map 里找有没有 sum - k,有的话说明 sum - k 是一个旧的sum,之前出现过。换句话说,新的sum - 旧的sum = k,说明 新的sum 减去 旧的sum,剩下的那一段的 和 等于k, ...
Given an array of integersnumsand an integerk. A continuous subarray is called nice if there arekodd numbers on it. Returnthe number of nice sub-arrays. Example 1: Input:nums = [1,1,2,1,1], k =3Output:2Explanation:The onlysub-arrayswith3odd numbers are [1,1,2,1]and[1,2,1,...
