K Pairs with smallest sum
Detailed guide and Python implementation for the 'K Pairs with smallest sum' problem.
Problem Statement
Write a function k_smallest_pairs(nums1, nums2, k) that takes two sorted integer arrays nums1 and nums2 and an integer k. Return the first k pairs [u, v] with the smallest sums, where u is from nums1 and v is from nums2, sorted by their sum in ascending order.
- •1 <= len(nums1), len(nums2) <= 10^4
- •1 <= k <= 1000
Examples
nums1 = [1, 7, 11], nums2 = [2, 4, 6], k = 3
[[1, 2], [1, 4], [1, 6]]
The smallest sum pairs are (1,2) sum=3, (1,4) sum=5, (1,6) sum=7.
