Answer 1

/* Input: Do Your Duty

* Output: Duty Your Do

*/

import java.io.*;

class RevSent

{

protected static void main()throws IOException

{

BufferedReader in=new BufferedReader(new InputStreamReader(System.in));

System.out.print("Enter the Sentence: ");

String s=in.readLine();

char ch; short a=0,b=0;

for(short i=0;i<s.length();i++)

{

ch=s.charAt(i);

if(ch==' ')

a++;

}

String w[]=new String[a+1];

for(short i=0;i<=a;i++)

w[i]="";

for(short i=0;i<s.length();i++)

{

ch=s.charAt(i);

if(ch==' ')

b++;

else

w[b]+=ch;

}

for(short i=a;i>=0;i--)

System.out.print(w[i]+" ");

}}

Answer 2

import java.io.*;

class RevWords

{

private byte wo(String s)

{

byte a=0;

for(byte i=0;i<s.length();i++)

{

if(s.charAt(i)==' ')

a++;

}

a++;

return a;

}

protected static void main()throws IOException

{

BufferedReader in=new BufferedReader(new InputStreamReader(System.in));

RevWords o=new RevWords();

System.out.print("Enter the String: ");

String s=in.readLine();

byte a=o.wo(s),b=0;

String w[]=new String[a];

for(byte i=0;i<a;i++)

w[i]="";

for(byte i=0;i<s.length();i++)

{

if(s.charAt(i)==' ')

b++;

else

w[b]+=s.charAt(i);

}

b=0;

for(byte i=0;i<a;i++)

{

for(byte j=(byte)(w[i].length()-1);j>=0;j--)

System.out.print(w[i].charAt(j));

System.out.print(' ');

}

}
