hi,

i don't know how 'long long int' work.

for example,

i hava input...

1 2
3 4
5 6
7 8


and first code,

#include <stdio.h>
int main()
{
long long int a, b;

while (scanf ("%lld%lld",&a, &b)!=EOF){
printf("%lld %lld\n", a, b);
}
return 0;

gives output

1 0
3 0
5 0
7 0 ...

i don't know why i got WA.
plz anybody help me... or give me sample input data... :D

here my code.

#include<iostream>
#include<string>
#include<stdio.h>
using namespace std;


bool isVowel(char c){
switch(c)
{
case 'a':
case 'e':
case 'i':
case 'o':
case 'u':
case 'y':
return true ...

you are right!

and i got accepted, with 'long double' .. ^^..

898989,
your idea looks, very impresive... ^^... i'll try it~

in problem 113 'Power of Cryptography' ,

i code,

long double n, k, p;

while (cin >> n >> p)
{

k = pow(p,(1/n));
printf("%.0lf\n", k);
}


and got WA. so~ so~ many times...
but,
double n, k, p;

while (cin >> n >> p)
{

k = pow(p,(1/n));
printf("%.0lf\n", k ...

this is my code.


#include <iostream>
#include <string>
#include <stdio.h>
using namespace std;

class BigInteger{
public:
string* str;
int sign;

public:
/* */
BigInteger(string a);
BigInteger(char* a);
BigInteger(int i);
BigInteger();

//
~BigInteger();


//
BigInteger& operator ...
