int main()
{
    char arr1[] = "welcome to bit!!!!!!";
    char arr2[] = "###################";
        int left = 0;
    int right = strlen(arr1) - 1;
        while (left <= right)
        {
            arr2[left] = arr1[left];
            arr2[right] = arr1[right];
            printf("%sn", arr2);
            left++;
            right--;
          }
        return 0;
