10070 - Leap Year or Not Leap Year and ...

[lbv]

Why got WA......please help.....

Hi,

• To post code, please use the "code" tags (see the button bar above the message editor).
• I suggest you start by taking the time to read the previous messages from this thread. There's a lot of noise, but also it's easy to spot the useful messages, with tips and test cases for you to try.
• Maybe the number in the input has more than 10^5 characters? My program assumes a maximum number of digits of about 10^6.

Try this case:

Input

Code: Select all

2100

Output

Code: Select all

This is huluculu festival year.

[hello]

Code: Select all

#include<stdio.h>

int main()
{

    int c15,c55,c100,c400,c4,ct=1,l,r,t;
    char arr[1000000];
    while(scanf("%s",arr)==1)
    {
        int i,k,q=0,rem=0,m=0,x=0,y=0;
        i=strlen(arr);
        for(k=0; k<i; k++)

Input: 2200
AC output: This is an ordinary year.

[nildorpon]

I got a Compile error.
Please take a look on my code and tell me whats wrong....

import java.io.BufferedInputStream;
import java.util.Scanner;

public class Main {
public static void main(String [] args){
Scanner scanner = new Scanner(new BufferedInputStream(System.in));
while(scanner.hasNext()){
int n = scanner.nextInt();
if(n<2000){
continue;
}
if(((n%4 == 0) && (n%100 != 0)) || (n%400 == 0)){
System.out.println("This is leap year.");
if(n%15 == 0){
System.out.println("This is huluculu festival year.");
}
if(n%55 == 0){
System.out.println("This is Bulukulu festival year.");
}
}else if(n%15 == 0){
System.out.println("This is huluculu festival year.");
}else{
System.out.println("This is an ordinary year.");
}
System.out.println();
}
}
}

You can click My Submissions to see the reason for your Compile Error. That code however gets RE. Try using BigInteger.

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

but i still get WA

A blank line should separate the output for each line of input. Don't print an extra blank line at the end.
One way to do that would be:

Code: Select all

bool first = true;
while(cin >> n) {
  if(!first)
    cout << endl;
  first = false;

  //the rest of your code goes here
}
