import java.util.*;
class GFG {
public String replacePi(String input)
{
String output = “”;

	int size = input.length(); 
	for (int i = 0; i < size; ++i) { 
		if (i + 1 < size && input.charAt(i) == 'p' && input.charAt(i + 1) == 'i') { 
			output += "3.14"; 
			i++; 
		} 
		else { 
			output += input.charAt(i); 
		} 
	} 
	return output; 
} 
public static void main(String args[]) 
{ 
	GFG g = new GFG(); 
    Scanner s=new Scanner(System.in);
    int n=s.nextInt();
    for(int i=0;i<n;i++){
	String input =s.nextLine(); 
	System.out.println(g.replacePi(input)); 
    }
}

}

why my this code is not being accepted
