Question

int i,l,p=0,j; char c; String s,w="",r="";

System.out.println("Enter a String");

s = sc.nextLine(); s = s.trim()+" "; l = s.length();

for (i=0;i<l;i++) {

c = s.charAt(i);

if (c != 32) 

w = w + c;

else { p++;

for (j=w.length()-1;j>=0;j--) {

c = w.charAt(j); r = r + c;

} if (w.compareToIgnoreCase(r) == 0 && r.length() > 1) 

System.out.println(w+"\t"+p);

w = ""; r = "";

}

if (i == l-1) {

p++;

for (j=w.length()-1;j>=0;j--) {

r = r + c;

}

if (w.compareToIgnoreCase(r) == 0 && r.length() > 1)

System.out.println(w+"\t"+p); }}}}

Q. Above coding will display palindrome words along with its position that is where it is present in the String. Add a statement to above coding so that it will display ''No palindrome words found" if there is not a single palindrome word present in the entered String.
