Why Wrong Ans Plz help

#include <iostream>
#include <cstdio>
using namespace std;

int main()
{
//freopen("in.txt", "r", stdin);
long long int t = 0;
string s;
while(cin >> s){
++t;
long long int l = s.size();
long long int a55 = 0, a15 = 0, a4 = 0, a100 = 0, a400 = 0;
for(long int i = 0; i < l; i++){
a55 = ((a55*10) + (s - 48)) % 55;
a15 = ((a15*10) + (s - 48)) % 15;
a100 = ((a100*10) + (s - 48)) % 100;
a4 = ((a4*10) + (s - 48)) % 4;
a400 = ((a400*10) + (s - 48)) % 400;
}
if(t > 1)
cout << endl;
bool flag = true;
if(a400 == 0 || (a4 == 0 && a100 != 0)){
cout << "This is leap year." << endl;
flag = false;
}
if(a15 % 15 == 0){
cout << "This is hulukulu festival year." << endl;
flag = false;
}
if((a400 == 0 || (a4 == 0 && a100 != 0))){
if( a55 == 0)
cout << "This is bulukulu festival year." << endl;
flag = false;
}
if(flag){
cout << "This is an ordinary year." << endl;
}
}
return 0;
}

huluculu is spelled wrong

Thanks a lot

Input:

Code: Select all

2000
12000
22000
32000
42000
52000
62000

Output should be:

Code: Select all

This is leap year.

This is leap year.
This is huluculu festival year.

This is leap year.
This is bulukulu festival year.

This is leap year.

This is leap year.
This is huluculu festival year.

This is leap year.

This is leap year.

Code: Select all

#include <iostream>
using namespace std;

int main(){
	long long year;
	while(cin >> year){
		bool leap = false, huluculu = false, bulukulu = false;
		if(year%4 == 0 && year%400 == 0) leap = true;
		else if(year%100 == 0) leap = false;
		if(year%15 == 0) huluculu = true;
		if(year%55 == 0 && leap) bulukulu = true;
		
		if(leap) cout << "This is leap year." << endl;
		if(huluculu) cout << "This is huluculu festival year." << endl;
		if(bulukulu) cout << "This is bulukulu festival year." << endl;
		if(!leap && !huluculu && !bulukulu) cout << "This is an ordinary year." << endl;
		cout << endl;
	}
}

Everything that I input is correct. But still it gives back a WA verdict. What could be the problem of my code?

[brianfry713]

The year can be bigger than a long long can handle, my AC code assumes a line can be up to 1000000 digits long.

So I will create a char, say char num[1000000], but here's the question:

How will I be able to convert every character to an integer so that i could check it if it is leap year or huluculu or bulukulu. Sorry. I'm still a newbie programmer.

You'll need to program a bigint mod function - search the web for examples. Or you could use Java's bigInteger.

import java.math.*;
import java.util.*;

	public static void main(String[] args){
		Scanner cin = new Scanner(System.in);
		BigInteger n;
		while(cin.hasNext()){
			n = cin.nextBigInteger();
			BigInteger fif = new BigInteger("15");
			BigInteger zero = new BigInteger("0");
			BigInteger hun = new BigInteger("100");
			BigInteger fhun = new BigInteger("400");
			BigInteger ffive = new BigInteger("55");
			BigInteger four = new BigInteger("4");
			
			boolean leap = false, huluculu = false, bulukulu = false;
			if(n.mod(four).equals(zero) && n.mod(fhun).equals(zero)) leap = true;
			else if(n.mod(hun).equals(zero)) leap = false;
			if(n.mod(fif).equals(zero)) huluculu = true;
			if(n.mod(ffive).equals(zero) && leap) bulukulu = true;
			
			if(leap) System.out.println("This is leap year.");
			if(huluculu) System.out.println("This is huluculu festival year.");
			if(bulukulu) System.out.println("This is bulukulu festival year.");
			if(!leap && !huluculu && !bulukulu) System.out.println("This is an ordinary year.");
			System.out.println();
		}
	}
}

Changed my code to Java using BigInteger yet I still receive a WA response from the judge. What could be the problem?

A blank line should separate the output for each line of input. Don't print an extra blank line at the end.

[partha31]

#include<stdio.h>
int main()
{
int n,a,b,c,count;
while(scanf("%d",&n)==1)
{
b==0;
count=0;
if(n%4==0&&n%100!=0||n%400==0)
{
printf("This is leap year.\n");
b++;
count++;
}
if(n%15==0)
{
printf("This is huluculu festival year.\n");
count++;
}
if(n%55==0&&b==1)
{
printf("This is bulukulu festival year.\n");
count++;
}
if(count==0)
printf("This is an ordinary year.\n");
}
return 0;
}
why is this getting WA

Your program doesn't pass the sample tests from the problem statement. Notice that blank lines are significant and the output from your program should match the expected output exactly.

Also try configuring your compiler to show you all warnings, and pay attention to those messages. For example, when I compiled your code I noticed this, which seems important:

Code: Select all

p.c: In function ‘main’:
p.c:7:1: warning: statement with no effect [-Wunused-value]
 b==0;
 ^
p.c:9:10: warning: suggest parentheses around ‘&&’ within ‘||’ [-Wparentheses]
 if(n%4==0&&n%100!=0||n%400==0)
          ^
