Why having WA with my code?

I am getting correct output of given simple input.
And also getting correct output as:
for 2100 huluculu,
for 22055 ordinary,
for 16555 ordinary .

I checked for int type also.
Where is the wrong?

Code: Select all

#include<stdio.h>
int main()
{
    freopen("10070.txt", "r", stdin);
    long long int lp,h,b,yr;
    while(scanf("%lld",&yr)!=EOF)
    {
        lp=h=b=0;
        if((yr%4==0 && yr%100!=0) || yr%400==0)
            lp=1;
        if(yr%15==0)
            h=1;
        if(lp==1 && yr%55==0)
            b=1;
        if(lp==1)
            printf("This is leap year.\n");
        if(h==1)
            printf("This is huluculu festival year.\n");
        if(b==1)
            printf("This is bulukulu festival year.\n");
        if(lp==0 && h==0 && b==0)
            printf("This is an ordinary year.\n");

        printf("\n");


    }
    return 0;
}

If there is a thread about your problem, please use it.
Don't open new thread. First of all use search by problem number (10070 for this problem)
http://acm.uva.es/board/search.php?keyw ... b3decb6507

For this problem there are many existing threads. One of them is below
http://acm.uva.es/board/viewtopic.php?f ... 07#p369473

The main reason why you get WA is the post written there

If you have problems read that posts.

By the way problems number is 10070 not 1070.

You must check input in this thread first. Your program gives wrong output. For example

osan wrote:please check this input & output. i hope these will help u.

INPUT
2200
3000
6000
2000
10500
5500
OUTPUT
This is an ordinary year.

This is huluculu festival year.

This is leap year.
This is huluculu festival year.

This is leap year.

This is huluculu festival year.

This is an ordinary year.

& one thing ur code is giving a extra blank line after last output. be careful about this.

please help me . i cannot find why wrong ans :

import java.math.BigInteger;
import java.util.Scanner;

public class Main {

private static Scanner scanner;

public static void main(String[] args) {
scanner = new Scanner(System.in);
BigInteger number;
boolean check;

while (scanner.hasNext()) {
number = scanner.nextBigInteger();

check=false;
if (number.mod(BigInteger.valueOf(4)).equals(BigInteger.ZERO)) {
if (number.mod(BigInteger.valueOf(100)).equals(BigInteger.ZERO)) {
if (number.mod(BigInteger.valueOf(400)).equals(BigInteger.ZERO)) {
System.out.println("This is leap year.");
check=true;
}
else {
check=false;
}
}
else {
System.out.println("This is leap year.");
check=true;
}
}
if (number.mod(BigInteger.valueOf(15)).equals(BigInteger.ZERO)) {
System.out.println("This is huluculu festival year.");
check=true;
}
if ( check==true && number.mod(BigInteger.valueOf(55)).equals(BigInteger.ZERO))
System.out.println("This is buluculu festival year.");
if(check==false )
System.out.println("This is an ordinary year.");
System.out.println();

}
}

}

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

I tried modular arithmatic to handle big input. I tried many inputs and it is okay. . . . May be i have formatting problems in my code. Can you help me with it please?

Code: Select all

Thanks! Code removed after AC

Try to check input in this thread first. I left 3 cases which your code fails.

Output:

This is huluculu festival year.

This is huluculu festival year.
If you can pass this input , hope your code will get A.C.

Don't forget to remove your code after getting accepted.

I passed those input. But still WA.

Code: Select all

Don't print blank line after last case.

Posted: **Fri Oct 10, 2014 1:40 pm**

what is the problem in my code

got WA three times

is there any critical input...

Code: Select all

GOT AC

Posted: **Fri Oct 10, 2014 3:15 pm**

You are printing extra character after last case.
Change reading to

Code: Select all

#include <iostream>
..
int ok = 0;
char ch;
while(std::cin.getline(num, 10000))   // gets(num) also works
{
    ..
    if (ok++) puts("");
        
    if(a==1)
    ..
    else if(a==0&&c==0)
        printf("This is an ordinary year.\n");
}
