Can you solve this real interview question? Number of Sub-arrays With Odd Sum - Given an array of integers arr, return the number of subarrays with an odd sum. Since the answer can be very large, return it modulo 109 + 7. Example 1: Input: arr = [
[leetcode] 1524. Number of Sub-arrays With Odd Sum Description Given an array of integers arr. Return the number of sub-arrays with odd sum. As the answer may grow large, the answer must be computed modulo 10^9 + 7. Example 1: Input: arr = [1,3,5] Output: 4 Explanation: All ...
1. create a prefix sum to index mapping. 2. scan the input array and keep a running sum. For each index i, get the shortest subarray of sum target in index [0, i]. Then get the subarray of sum target in [i + 1, N - 1] if exists. Return the best result after going through...
Given an array of integers arr and an integer target. You have to find two non-overlapping sub-arrays of arr each with sum equal target. There can be multiple answers so you have to find an answer where the sum of the lengths of the two sub-arrays is minimum. Return the minimum sum ...

PHP 使用 array_unique 对一维数组去重 报Array to string conversion的原因 官方文档说明: 默认是已字符串的方式去比较值是否相等,在某些php版本中,如果一维数组是中的值是整型,则会报:Array to string conversion,这时候加上第二个参数 SORT_NUMERIC (按照数值类型比较)就没问题了。 sort_flags 第二个可选参数...
