Is is possible to make System.out.print sort variables in a reverse order? I know I can use Strings and reverse it but I am wondering if its possible to do this with System.out.print directly in java. Thank you:)

After submission it says the answer is wrong, please tell me what is the logical error in it and not about the formatting or other ways to do it.

public class Solution {  public static String reverse(String s1){    int i=s1.length()-1;    String s2="";    while(i>=0){        s2=s2+s1.charAt(i--);         }    s2=s2+' ';    return s2;  }    // Return the reversed string. No need to print  public static String reverseEachWord(String s1) {      s1=s1+"";    String s2="";    int i=0;    char ch;    String temp="";    while(i<s1.length()){      ch=s1.charAt(i);      if(ch!=' '){        temp=temp+ch;        i++;        }      else{        temp=reverse(temp);        s2=s2+temp;        temp="";        i++;      }    }    return s2;      }}

I am trying to return a string from a function but the code doesn't seem to work. My assignment requires no use of C++ STL.

include<iostream>using namespace std;string reverse (string input){      string rev;    for (int i=input.length()-1;i>=0;i--){        rev[i]=input[i];    }    return rev;}int main() {    string input;    cout<<"Enter the string:";    cin>>input;    string revInput = reverse(input);    cout <<revInput;}

How to print the reverse of the String java is object orientated language without using any predefined function like reverse()?

How do you reverse a string in C or C++ without requiring a separate buffer to hold the reversed string?
