int decimal(char s1[])
{
int i,n,sum=0;
n=strlen(s1);
for(i=n-1;i>=0;i--)
{
if(s1[i]=='A')
sum+=(10*pow(16,n-i-1));
else if(s1[i]=='B')
sum+=(11*pow(16,n-i-1));
else if(s1[i]=='C')

I m still TLE..but it's work for all critical i/0..
here is my code.

Can anyone plz tell me How can I evaluate the formula when R>(l+w)??

{
z=0;
news=sqrt(i);
for(j=3;j<=news;j+=2)
if(i%j==0)
{

k++;
}
}
scanf("%ld",&n);
if(n==0)

Thanks to Jan, My answer has improved but still I m getting TLE:(.. it's not working for input 1000000..
anymore suggestion form anybody???

Can anyone please tell me why I m getting RE in this program??

How can I use Bigint in C++?

can anyone please tell me what is the prob in my following code>
what data type I should use?
#include<stdio.h>

long long f(long long n)
{
long long x=1,z,y=0;
if(n>3)
x=n*(n-1)*(n-2)*(n-3);
z=(x/24);
if(n>1)
y=((n*(n-1))/2);
return (y+z+1);
}

main()
{
long long a[3500],b[3500],s,n;
int i ...

How this algorithm works?
