Can someone please tell me what is wrong with this episode?
Thank you in advance!!

174

have a look at your inner if where you’ve mentioned x>y
don’t forget about bank charges as well… so your condition should be

if(x % 5 == 0 && y >= x+0.5)

just this one if would work

	}
	else {
		System.out.printf("%.2f",f);
	}

}
}

whats wrong here??

178

#include <stdio.h>

int main(void) {
// your code goes here
int X;float Y;
scanf("%u",&X);
scanf("%f",&Y);
if(0<Y<=2000){
if((X%5==0)&&(Y>=(X+0.50))){
Y=Y-(X+0.5);
printf("%.2f",Y);
}
else{
printf("%.2f",Y);
}
}
return 0;
}

here is the correct answer

179

#include <stdio.h>

int main(void) {
int x;
float y;
scanf("%d %f",&x,&y);
if(x%5==0 && (y>(x+0.50)))
y=y-x-0.50;
printf("%0.2f",y);
}

can anyone help me where i’m going wrong.??

180

its y>=(x+0.50)
and take format specifier for x as %u so that it takes only positive integers

181

#include <stdio.h>

int main(void) {

int x;

float z,y,m;

scanf("%d",&x);// withdraw

scanf("%f",&y);// available

z=x%5;

if(0<x<=2000 && 0<y<=2000 && y>x && z == 0)

{

    m=(y-x)-.50;

    printf("%f",m);

}

else if(z!=0)

{

    printf("%f",y);

}

else if (x<y)

{

    printf("%f",y);

}

return 0;

} showing wrong

[KOTLIN]

import java.util.*

val charge: Float = 0.50f

fun main(args: Array) {
val reader = Scanner(System.in)
var input: Int = reader.nextInt()
var balance: Float = reader.nextFloat()

if (isWithdrawCorrect(input) && isBalanceCorrect(balance) && isAccountBalanced(input, balance) && isMultipleOfFive(input)){
    println("%.2f".format(balance - input - charge))
} else {
    println("%.2f".format(balance))
}

}

fun isAccountBalanced(input: Int,input1: Float): Boolean = (input1 - input - charge) > 0

fun isMultipleOfFive(input: Int): Boolean = (input % 5 == 0)

fun isWithdrawCorrect(withdraw: Int): Boolean = 0 < withdraw && withdraw <= 2000

fun isBalanceCorrect(balance: Float): Boolean = 0 <= balance && balance <= 2000

i dont get it. examples are working fine.

183

nvm… isAccountBalanced was broken. it needed to be >= 0 not > 0 :smiley:

What is wrong with the code? It gives the correct output with sample cases but upon submission it shows wrong answer.

a,b = map(float, input().split())
if (a+0.5<=b):
if(a%5==0):
print("{:.2f}".format(b-a-0.50))
else:
print("{:.2f}".format(b))
else:
print("{:.2f}".format(b))

185

The code gives correct output with sample cases but shows wrong answer upon submission. Can anyone please help me with it?

x,y = input().split()
x = int(x)
y = float(y)
if(x%5 == 0 and y>(x+0.50)):
print((y-x-0.5))
else:
print("%.2f" %y)

186

change that to:

if(x % 5 == 0 and y >= (x + 0.5)):

Heres my working solution:

#include <iostream>
using namespace std;

int main() {
int a;
float b;
cin >> a >> b ;

if (a > (b - 0.5)) { cout << b ; }
else if(a % 5 !=0 ) { cout << b; }
else { cout << (b - a - 0.5); } 

return 0;

}

188

Please Explain why my code is wrong in Custom Input everything is correct but when I submit it says Wrong Answer

//Atm Problem

#include

#include<bits/stdc++.h>

using namespace std;

int main() {

int a;

double b;



cin>>a>>b;



if((a % 5 == 0) && (b > (a + 0.50))){

    cout<<fixed<<setprecision(2)(b-a-0.50);

}

else{

    

    cout<<fixed<<setprecision(2)<<b;

}



return 0;

}

Can anyone help me, what’s the Error in this code?

191

Isn’t it supposed to be

b >= (a + 0.50) ?
