My code

#include <stdio.h>
void printPattern(int n) {
    for (int i = 0; i < n; i++) {
        for (int j = 0; j < n - i; j++) {
            printf("*");
        }
        for (int j = 0; j < 2 * i; j++) {
            printf(" ");
        }
        for (int j = 0; j < n - i; j++) {
            printf("*");
        }
        printf("\n");
    }
    for (int i = n - 1; i >= 0; i--) {
        for (int j = 0; j < n - i; j++) {
            printf("*");
        }
        for (int j = 0; j < 2 * i; j++) {
            printf(" ");
