{
int n=s.length();
String s1="";
for(int i=n-1; i>=0; i--)
{
s1=s1+s.charAt(i);
}
S.o.p(s1);
}
}

2)
import java.util.*;
class Check
{
void main()
{
Scanner sn=new Scanner(System.in);
S.o.p("Enter a string - ");
String s=sn.nextLine();
S.o.p("Enter the word to be searched - ")
String s1=sn.nextLine();
s=s.toLowerCase();
int n=s.length();
int count = 0;
for(int i=0; i<=n-1; i++)
{
if((s1.charAt(i))equals(s.charAt(j)))
{
count++;
}
}
S.o.p("frequency - "+ count);
}
}
