X, Y = input(’’).split()
X = float(X)
Y = float(Y)
if X%5 == 0 and X + 0.5 < Y:
Y=Y - X - 0.50
else:
Y=Y
print(Y)
why is this not working?
using namespace std;
int main()
{
int y,x;
cin>>x>>y;
if ( (x%5==0) && (x < (y+.50)))
cout << (y - x) - 0.50;
else
cout<<y;
return 0;
}
//----> what is wrong in this? why my memory limit is exceeding and it is showing approx15000kb?
You have to return value not print.
x,y=input().split()
y=float(y)
x=float(x)
if (x%5==0.00 and x>0 and y>=0 and x<=2000 and y<=2000):
if (float(x)<(y-0.50)):
print(f"{(y - float(x) - 0.50):.2f}",)
else:
print(f"{y:.2f}")
else:
print(f"{y:.2f}")
it shows error
you look new in competitive programming as you use printf. Its good think to add printf and make your code beautifull but its not needed in competitive programming though.
#include
using namespace std;
int main() {
// your code goes here
//variables
int X, Y; // X is need, Y is balance
float fee = 0.5; // bank fee
cin >> X >> Y; // reads and stores X and Y
float fx = X; // turns them into floats
float fy = Y;
if( X%5 == 0)//Checks if need is divisible by 5
{
if( X < Y) // checks if X is less than balance
{
fy -= fx;
fy -= fee;
printf("%.2f", fy); // prints new balance
}
else // if x is greater prints old balance
{
printf( "%.2f", fy);
}
}
else // if x is not divisible by 5, prints out old balance
{
printf( "%.2f", fy);
}
return 0;
}
(This solution was longer than all the ones i saw but it worked well for me, when i kept custom inputs it always worked but once i submitted it it always marked it as wrong. It executes in under 1 second and uses 15.232 kb)
Why take the inputs into Integers when it is mentioned that Y will be a Number?
It should have been if(X + fee <= Y) instead.
#include
using namespace std;
int main() {
int x, tot;
float bal;
cin>>x>>tot;
if (x <= tot- 0.5 )
{
if (x%5==0)
bal= tot- x - 0.5;
}
else
{
bal= tot;
}
cout<<"\n"<<bal;
}
Program is showing correct output as given but while submission, it is showing wrong…
Why??
You should at least read the previous comments before blindly posting your code and asking for help.

Could anyone tell me what should I change to make it correct. There are compilation errors but on submitting it, I get a WRONG ANSWER.
Please someone help me out!!

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

whats wrong here??

// your code goes here
int X;float Y;
scanf("%u",&X);
scanf("%f",&Y);

Y=Y-(X+0.5);
printf("%.2f",Y);
}
else{
printf("%.2f",Y);
}
}
return 0;
}
here is the correct answer
#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.??
its y>=(x+0.50)
and take format specifier for x as %u so that it takes only positive integers
#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

import java.util.*
val charge: Float = 0.50f

val reader = Scanner(System.in)

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