Help me with this avg word count problem.

Question

import java.util.*;
public class Program
{
public static void main(String[] args) {
Scanner s=new Scanner(System.in);
String str=s.nextLine();
String arr[]=str.split("\\s+");
for(int i=0;i<str.length();i++)
if((str.charAt(i)>=32 &&str.charAt(i)<=64))
{
str=str.replaceAll("str.charAt(i)","");
}
else {}
int n=str.length();
int ans=n/arr.length;
System.out.println(ans);
}
}

Answer 1

Ajay, your for loop is running but not reacting according to your desire.

Since you have used "" for the replacement of char at index i and so the compiler will take this as String type.

You can replace that replacing statement with this one:
str=str.replace(Character.toString(str.charAt(i)),"");

Also, output wants the nearest whole num; and as mentioned in the question if your ans= 5.2, output = 6.
And to fulfill that condition, you may use:
double n=str.length();
double ans= n/arr.length;

if (ans == (int) (Math.floor(ans))){
ans = ans;
}else{
ans++;
}
System.out.println((int)ans);
}
}

I hope it works!
