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

[aaa111]

Why am i getting wrong answer, i checked all output,they seems right to me:

Code: Select all

#include<stdio.h>

    return 1;

Check this:

234234444444
your output:

This is leap year.
This is bulukulu festival year.

My Acc output:

This is leap year.

No way to be bulukulu festival year because not divisible by 55.


To:> iceb3rg

check this:

67665777776000000000000000000000000
6666666666666000600600000000066

your program output:

This is leap year.

This is leap year.

But My Acc output:

This is leap year.

This is an ordinary year.


But if u only test this input 6666666666666000600600000000066. then it outputs correctly.This means you have flaging problem.reinitialize everything before next input.

Did you notice that in problem statement:-

the Bulukulu festival (Happens on years divisible by 55 provided that is also a leap year).

Read the problem statement carefully.And why you are creating new thread for every question ? there is a search box
in every volume.Insert your problem no. here and use the existing thread to ask your question.


Good luck.

Can someone find problem in my solution?
in my code d3, d4, d5, d11, d100, d400 are 1 if the input is divisible by the respective number.

Code: Select all

				puts("This is huluculu festival year.");
			}
			if (bulu){
				puts("This is buluculu festival year.");
			}
		}
	}
	
	return 0;
}

void div3(){
	int s=0;
	for (i = 0; i < L; i ++){
		s+=Y[i];
	}
	
	d3 = (s%3 == 0);
}

	int n = 0;
	n += (Y[L-1]);
	n += (10*Y[L-2]);
	
	d4 = (n>>2<<2 == n);

[plamplam]

There is no blank line after the last output.

[plamplam]

@tanvir09 change this part of your code
if(bul==1)printf("This is bulukulu festival year.\n"); to
if(bul==1 && lip == 1)printf("This is bulukulu festival year.\n");
Also you are printing an extra newline after eof.
And btw you are indeed very careless. Look carefully there is a '.' (full-stop) after leap year. Get AC and remove your code ASAP

[Crocodile_009]

i can't understand why my code gets WA
here is my code:

#include<stdio.h>
int main()
{
int year,temp;
while(scanf("%d",&year)==1)
{
printf("\n");
if( ((year%4==0)&&(year%100!=0)) ||(year%400==0) ){

printf("This is leap year.\n");
if(year%15==0){
printf("This is huluculu festival year.\n");
if(year%55==0){
printf("This is buluculu festival year.\n");
}
}
}
else if(year%15==0){
printf("This is huluculu festival year.\n");
}
else if(year%55==0&&year%100!=0){
printf("This is buluculu festival year.\n");
}
else
printf("This is an ordinary year.\n");

}
return 0;
}

The input may be too large to fit into an int.
