int binary_search(int arr[], int n, int target) {
    int left = 0, right = n - 1;
    while (left <= right) {
        int mid = (left + right) / 2;
        if (arr[mid] == target)
            return mid;
        else if (arr[mid] < target)
            left = mid + 1;
        else
            right = mid - 1;
    }
    return left;
}

int main() {
    int n, q, i, target;
    scanf("%d %d", & n, & q);
    int arr[n];
    for (i = 0; i < n; i++)
        scanf("%d", & arr[i]);
    for (i = 0; i < q; i++) {
        scanf("%d", & target);
