def find_average(arr): n = len(arr) cnt = 0 i, j = 0, n - 1 while i < j: mid = (arr[i] + arr[j]) / 2 if mid in arr and mid != arr[i] and mid != arr[j]: cnt += 1 if mid < arr[0]: i += 1 elif mid > arr[-1]: j -= 1 else: if mid > arr[i+1]: i += 1 elif mid < arr[j-1]: j -= 1 else: i += 1 j -= 1 return cnt 把这段代码改为c语言

以下是将该Python代码转换为C语言的代码：

#include <stdio.h>

int find_average(int arr[], int n) {
    int cnt = 0;
    int i = 0, j = n - 1;
    while (i < j) {
        int mid = (arr[i] + arr[j]) / 2;
        int k;
        int mid_in_arr = 0;
        for (k = 0; k < n; k++) {
            if (arr[k] == mid && mid != arr[i] && mid != arr[j]) {
                mid_in_arr = 1;
                break;
            }
        }
        if (mid_in_arr) {
            cnt++;
        }
        if (mid < arr[0]) {
            i++;
        } else if (mid > arr[n-1]) {
            j--;
        } else {
            if (mid > arr[i+1]) {
                i++;
            } else if (mid < arr[j-1]) {
                j--;
            } else {
                i++;
                j--;
            }
        }
    }
    return cnt;
}

int main() {
    int arr[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
    int n = sizeof(arr) / sizeof(arr[0]);
    int cnt = find_average(arr, n);
    printf("%d\n", cnt);
    return 0;
