    373 - Find K Pairs with Smallest Sums.

    Medium

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

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

    Return the k pairs <code>(u<sub>1</sub>, v<sub>1</sub>), (u<sub>2</sub>, v<sub>2</sub>), ..., (u<sub>k</sub>, v<sub>k</sub>)</code> with the smallest sums.

    Example 1:

    Input: nums1 = 1,7,11, nums2 = 2,4,6, k = 3

    Output: [1,2,1,4,1,6]

    Explanation: 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

    Example 2:

    Input: nums1 = 1,1,2, nums2 = 1,2,3, k = 2

    Output: [1,1,1,1]

    Explanation: 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

    Example 3:

    Input: nums1 = 1,2, nums2 = 3, k = 3

    Output: [1,3,2,3]

    Explanation: All possible pairs are returned from the sequence: 1,3,2,3

    Constraints:

    • <code>1 <= nums1.length, nums2.length <= 10<sup>5</sup></code>

    • <code>-10<sup>9</sup><= nums1i, nums2i<= 10<sup>9</sup></code>

    • nums1 and nums2 both are sorted in ascending order.

    • <code>1 <= k <= 10<sup>4</sup></code>
