keep doing {
   digit = origin number % 10,
   reverse = reverse * 10 + digit,
   subtract digit from origin number and also origin number /= 10
} until origin number % 10 give u zero

public class ReverseNumberWithoutVectors {

    public static void main(String[] args) {
        int i = 54321;
        int o = 0;
        
        while(i > 0) {
            int k = i % 10;
            o = o*10 + k;
            i = i/10;
        }
        System.out.println(o);
    }
}

function reverse_uint(original) {
    reversed = 0;
    while (original > 0) {
        digit = original % 10;
        original = original / 10;
        reversed = reversed * 10 + digit;
    }
    return reversed;
}

Use recursion to print in the correct order. It will be automatically printed reverse way.
