How do you find the nearest palindrome of any number?

Answer 1

int nearPalin(int n){ int temp = n; int count = 0; while(temp>0){ temp /= 10; count++; } if(count%2 == 0){ count = count/2; while(count--) n = n / 10; temp = n; while(n>0){ temp = temp*10 + n%10; n = n/10; } return temp; } else{ count = count/2; while(count--) n = n / 10; temp = n; n = n/10; while(n>0){ temp = temp*10 + n%10; n = n/10; } return temp; } }
