1. Create an array called best[] and init all its values to Integer.MAX_VALUE. best[i] stores the length of the shortest subarray with sum target that ends at index <= i. 2. Use sliding window + two pointers to find each matching subarray that ends at each index. There should be ...
A subarray is a contiguous non-empty sequence of elements within an array. Example 1: Input: nums = [4,2,4]Output: trueExplanation: The subarrays with elements [4,2] and [2,4] have the same sum of 6. Example 2: Input: nums = [1,2,3,4,5]Output: falseExplanation: No two sub...
A similar idea can be used to partition an array into two subarrays where values from one array are strictly less than values from another array. 1classSolution {2publicstaticvoidmain(String[] args) {3Solution solution =newSolution();4System.out.println(solution.canPartition(newint[]{11, ...

Return an array of all good indices sorted in increasing order.Example 1:Input: nums = [2,1,1,1,3,4,1], k = 2 Output: [2,3] Explanation: There are two good indices in the array: - Index 2. The subarray [2,1] is in non-increasing order, and the subarray [1,3] is in ...
Given an integer array, return the k-th smallest distance among all the pairs. The distance of a pair (A, B) is defined as the absolute difference between A and B. Example 1: Input: nums = [1,3,1] k = 1 Output: 0 Explanation: ...
