M × N o'lchamli matrix matritsasi va qator indekslari K1, K2 (0 dan boshlab) berilgan. K1 va K2 qatorlarining o'rnini almashtirib, natijani qaytaring.
func swapRows(M int, N int, K1 int, K2 int, matrix [][]int) [][]int {
// ...
}
Input: M=3, N=3, K1=0, K2=2, matrix=[[1,2,3],[4,5,6],[7,8,9]]
Output: [[7, 8, 9], [4, 5, 6], [1, 2, 3]]
Input: M=4, N=2, K1=1, K2=3, matrix=[[10,20],[30,40],[50,60],[70,80]]
Output: [[10, 20], [70, 80], [50, 60], [30, 40]]
Input: M=2, N=4, K1=0, K2=1, matrix=[[1,2,3,4],[5,6,7,8]]
Output: [[5, 6, 7, 8], [1, 2, 3, 4]]
m[K1], m[K2] = m[K2], m[K1].
