Answer:
/ReversedEvenOddString.java
import java.util.Scanner;
public class ReversedEvenOddString {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String s = sc.nextLine();
String evens = "";
String odds = "";
for(int i = s.length()-1;i>=0;i--){
if(i%2==1){
odds += s.charAt(i);
}
else{
evens += s.charAt(i);
}
}
String res;
if(s.length()%2==1){
res = evens+odds;
}
else{
res = odds+evens;
}
System.out.println(res);
}
}

See the code below and the algorithm explanation on the figure.
Explanation:
The explanation in order to get the answer is given on the figure below.
Solving this problem with C. The program is given below:
#include <stdio.h>
int main(void) {
int n, Even=0, Odd=0, Zeros=0;
for (;;) {
printf("\nEnter the value the value that you want to check(remember just integers): ");
//IF we input a non-numeric character the code end;
if (scanf("%d", &n) != 1) break;
if (n == 0) {
Zeros++;
}
else {
if (n % 2) {
Even++;
}
else {
Odd++;
}
}
}
printf("for this case we have %d even, %d odd, and %d zero values.", Even, Odd, Zeros);
return 0;
}
