I can’t find the mistake in my code but Jude showing wrong ans at test case 9 … dont konow for which input my code is wrong ,can anyone help me
code:
#include<bits/stdc++.h>
using namespace std;
int main()
{
int t;
cin>>t;
while(t–)
{
long long int counter =0,counter1=0,counter2=0,counter3=0,counter4=0,counter5=0;
long long int n,m,a,d;
cin>>n>>m>>a>>d;
long long int r = (n/a+1)*a;
long long int i=r;
while(i<=m)
{
counter1++;
i = i+a;
}
r = (n/(a+d)+1)*(a+d);
i= r-a-d;
while(i<=m)
{
i = i+a+d;
if(i%a==0)continue;
counter2++;
}
r = (n/(a+2*d)+1)*(a+2*d);
i= r-a-2*d;
while(i<=m)
{
i = i+a+2*d;
if(i%a==0)continue;
if(i%(a+d)==0)continue;
counter3++;
}
r = (n/(a+3*d)+1)*(a+3*d);
i= r-a-3*d;
while(i<=m)
{
i = i+a+3*d;
if(i%a==0)continue;
if(i%(a+d)==0)continue;
if(i%(a+2*d)==0)continue;
counter4++;
}
r = (n/(a+4*d)+1)*(a+4*d);
i= r-a-4*d;
while(i<=m)
{
i = i+a+4*d;
if(i%a==0)continue;
if(i%(a+d)==0)continue;
if(i%(a+2*d)==0)continue;
if(i%(a+3*d)==0)continue;
counter5++;
}
counter = counter1+counter2+counter3+counter4+counter5;
long long int total = m-n+1;
cout<<total-counter<<endl;
}
return 0;
}
