Pls follow the approach as :

long long int student(long long int n,long long int m,long long int x,long long int y)
{
long long int l = 1;
long long int h = n;
long long int ans;
while(l<=h)
{
long long int mid = (l+h)/2;
if(mid*x <= m +(n-mid)y)
{
ans = mid;
l = mid+1;
}
else
if(midx > m +(n-mid)*y)
{
h = mid -1;
}
}
return ans;
}
