Where the code is wrong?

``````#include<stdio.h>

int main() {
int a, b, c, d, e;
scanf("%d %d %d", &a, &b, &c);
d = b + c;
b = a * b/d;
c = a * c/d;
printf("%d %d", b, c);
return 0;
}
``````

The code gives wrong in the 6th test case.

Check your code with big numbers like 231-1. Your code fails to give write answers when it gets INT_MAX as x (the summation of the numbers).

Dear why I gettin wa in last case???

@Rubel47
I checked your code with this case. But your code’s output dissapointed me.

Your method is quite wrong. (But somehow it passed previous test cases!)

``````#include<iostream>
using namespace std;
int main()
{
unsigned long long n,m,r,div,mul2,mul,sum;
cin>>n>>m>>r;
sum=m+r;
div=n/sum;
mul=div*m;
mul2=div*r;
cout<<mul<<" "<<mul2<<endl;
}
``````

this code gives wrong 7th test case.why??

You’ll get CompilationError on this code. But I saw your original submission. Did you checked your code with the previous comment’s input? Your code fails there. Now find a solution.

7th test case produce wrong ans. bt why?

``````#include <stdio.h>
int main(){
long long x, m, n, temp;
scanf("%lld%lld%lld",&x,&m,&n);
temp=x/(m+n);
m=m*temp;
n=n*temp;
printf("%lld %lld\n",m,n);
return 0;
}
``````

“Have you checked your code for this input??”

``````#include<iostream>
using namespace std;
int main()
{
int y,p,q,a,b,c,x;
cin>>a>>b>>c;
x=b+c;
y=a/x;
p=y*b;
q=y*c;
cout<<p<<" "<<q;
}
``````

The code gives wrong in the 7th test case.

Have you checked your code for this input?

#include<bits/stdc++.h>
using namespace std;
int main(){
long long int x,m,n,mult;
cin>>x>>m>>n;
mult=x/(m+n);
cout<<mmult<<" "<<nmult<<endl;
return 0;
}

why the testcase 7 is wrong? I got the same ans as u.

Watch previous replies.

Why is it showing wrong answer on test case 7😧

#include<stdio.h>
int main()
{
int x,m,n;
scanf(“%d%d%d”,&x,&m,&n);
int fst,scnd;
fst=(x/(m+n))*m;
scnd=x-fst;
printf(“%d %d”,fst,scnd);
}
