how to reverse the digit code example
Example 1: reverse number in java
public class ReverseNumber {
public static void main(String[] args) {
int num = 1234, reversed = 0;
while(num != 0) {
int digit = num % 10;
reversed = reversed * 10 + digit;
num = num / 10;
}
System.out.println("Reversed Number: " + reversed);
}}
Example 2: reverse a number in c
#include <stdio.h>
int main() {
int n, rev = 0, remainder;
printf("Enter an integer: ");
scanf("%d", &n);
while (n != 0) {
remainder = n % 10;
rev = rev * 10 + remainder;
n /= 10;
}
printf("Reversed number = %d", rev);
return 0;
}
Example 3: print reverse number
void printReverse(int n) {
if (n < 1) return;
cout << n << endl;
printReverse(n - 1);
}
printReverse(10);
