Save the first element, shift everything left, put it at the end.

Solution explanation

k % n avoids doing full rotations that change nothing.

#include <stdio.h>

int main() {
    int n, k, a[100];
    scanf("%d", &n);
    for (int i = 0; i < n; i++) scanf("%d", &a[i]);
    scanf("%d", &k);
    k = k % n;
    for (int step = 0; step < k; step++) {
        int first = a[0];
        for (int i = 0; i < n - 1; i++) a[i] = a[i + 1];
        a[n - 1] = first;
    }
    for (int i = 0; i < n; i++) {
        printf("%d", a[i]);
        if (i < n - 1) printf(" ");
    }
    printf("\n");
    return 0;
}
