The "C language" finds a separate number in the array of two number pairs that appear.

A separate number is found in the array of two number pairs that appear. For example, {a. 3,1,4. 2}, that is, find 4#include <stdio.h>int find (int arr[], int len) {int i = 0;int ret = 0;for (i = 0; i < len; i++) {ret = Ret^a Rr[i];} return ret;} int main () {int arr1[] = {1, 2, 2, 3, 1, 5, 3};int arr2[] = {1, 2, 3,1,2,3,5,5,4,6,4};p rintf ("%d\n", find (arr1, sizeof ( ARR1)/sizeof (arr1[0]));p rintf ("%d\n", find (arr2, sizeof (ARR2)/sizeof (arr2[0]))); return 0;}
