You are given two integer arrays nums1 and nums2 sorted in ascending order and an integer k.

\n\n

Define a pair (u, v) which consists of one element from the first array and one element from the second array.

\n\n

Return the k pairs (u1, v1), (u2, v2), ..., (uk, vk) with the smallest sums.

\n\n

Example 1:

\n\n
\nInput: nums1 = [1,7,11], nums2 = [2,4,6], k = 3\nOutput: [[1,2],[1,4],[1,6]]\nExplanation: The first 3 pairs are returned from the sequence: [1,2],[1,4],[1,6],[7,2],[7,4],[11,2],[7,6],[11,4],[11,6]\n
\n\n

Example 2:

\n\n
\nInput: nums1 = [1,1,2], nums2 = [1,2,3], k = 2\nOutput: [[1,1],[1,1]]\nExplanation: The first 2 pairs are returned from the sequence: [1,1],[1,1],[1,2],[2,1],[1,2],[2,2],[1,3],[1,3],[2,3]\n
\n\n

Example 3:

\n\n
\nInput: nums1 = [1,2], nums2 = [3], k = 3\nOutput: [[1,3],[2,3]]\nExplanation: All possible pairs are returned from the sequence: [1,3],[2,3]\n
