K-pairs with smallest sum in two arrays in C++ PrepInsta
WebFind a pair with the given sum in an array Given an unsorted integer array, find a pair with the given sum in it. For example, Input: nums = [8, 7, 2, 5, 3, 1] target = 10 Output: Pair found (8, 2) or Pair found (7, 3) Input: nums = [5, 2, 6, 8, 1, 9] target = 12 Output: Pair not found Practice this problem Web2 days ago · i. Remove the largest pair from the result vector. ii. Add the current pair (i, j) and its sum to the result vector. Repeat steps 3-5 for all pairs of indices. After processing all pairs, the result vector will contain the k pairs with the smallest sum. Return the result vector. Note The time complexity of this brute force method is O (n1 * n2 ... WebFeb 15, 2024 · Iterate each row of the matrix mat and find the number of soldiers present in each row using binary search since all soldiers will be present at the beginning so each row is by default sorted in descending order. After finding the number of soldiers in each row, push it into the max_heap along with the current row_index ( i ). dvr-204u-k1
