Are you sure that your output is upto 2nd decimal place @anany_097?

because 120.000 is NOT 120.00 and hence would be flagged wrong.
Also, e is the money to be withdrawn. make sure that e is a multiple of 5.

Can anyone tell me that why the Codechef mark it as a wrong answer?

    #include <stdio.h>
 
    int main(void) {
	int x; //amount to withdraw
	float y; 	//initial balance
	
	scanf("%d %f",&x,&y);
	if((x>0) && (x<=2000) && (y>=0) && (y<=2000))
	{
		if((x<y) && (x%5 ) == 0)
			printf("%.2f",y-x-0.50);
		else
			printf("%.2f",y);
	}
	
	return 0;
}

withdraw**+0.50**>bankamount
This condition is necessary when in input is :
120 120.00
output should be :
120.00
not :
-0.50

ak1107 · March 16, 2017, 6:27pm

#include <stdio.h>

int main(void)

{
int x=0;

float y=0;

scanf("%d",&x);

scanf("%f", &y);

if((x%5==0)&&(x<y))

{
    y = y - x - 0.50;

   printf("%.2f", y);

}

else

printf("%.2f", y);

return 0;

}

how is this a wrong answer?

vijju123 · March 16, 2017, 6:38pm

if((x%5==0)&&(x<y))-This is faulty, as y should be greater than x+0.5, as problem clearly says "enough cash to perform the withdrawal transaction (including bank charges). "

Make changes and get back to me in case of discrepancy

package main

import (
“strconv”
“fmt”
“math”
)
func main(){

fmt.Print("Enter Amount : ")

var amount string

fmt.Scanln(&amount)

var ar float64

i, _ := strconv.ParseFloat(amount,64)

h := math.Mod(i, 5.0)

if i <= 2000{

if h != 0 {

fmt.Print(ar)

}

if h == 0{

var va float64

va = ar - i - 0.50

fmt.Print(“Balance :”)

fmt.Print(va)
}
}

if i > 2000 {

fmt.Print(ar)

}

I wrote this code in go ,it works fine in my laptop ,but not in codechef. Is there any problem with it?

hruday968 · June 4, 2017, 4:06pm

Don’t print any statements,printing only answer is enough

vani_24 · June 4, 2017, 5:20pm

import java.util.Scanner;

class Atm{

public static void main(String[] args){

	Scanner s=new Scanner(System.in);
	System.out.println("enter amt to be withdrawn:");
	double a=s.nextDouble();
	System.out.println("enter the current amout in account");
	double b=s.nextDouble();
	if((0<a)&&(0<b)){
		if((a<=2000.0)&&(b<=2000.0)){
			if(a>b) System.out.println(b);
			if((a%5)!=0) System.out.println(b);
			if(((a%5)==0)&&(a==b)) System.out.println(b-a);
			if(((a%5)==0)&&(a<b)) System.out.println((b-a)-0.50);
		}
	}
}

}

whats wrong with this code?

ayan_nitd · June 4, 2017, 8:10pm

Follow standard input/output format. Don’t print those "enter amt … " etc.

now also it shows wrong answer! whats wrong now.? output is coming right in my compiler.

what is wrong with this code? it is working perfectly in BlueJ but showing WA in CodeChef compiler

Hey @skbly7 -

Q isnt properly closed, common bug when we click on close button twice.
Why close an editorial? People usually come to editorials to ask doubt, so why close it???
