661 - Blowing Fuses

[cyberdragon]

What a silly mistake !
Thanks.

Output a blank line after each test case.

What brianfry713 mentioned is true. I'd like to elucidate on this some more. For the following input

Code: Select all

5 3 9
7
6
6
7
2
3
2
2
3 9 10
5
3

3
2
3
3
2
1
1
3
2
1 1 20
20
1
0 0 0

The AC output is

Code: Select all

Sequence 1
Fuse was blown.

Sequence 2
Fuse was not blown.
Maximal power consumption was 10 amperes.

Sequence 3
Fuse was not blown.
Maximal power consumption was 20 amperes.

As expected, there's a blank between sequences. However, note that there's also a blank line after the last output. If you don't print this blank line, your code will get a WA.

got AC !! Thank u All for help ...

The input will be terminated by a test case starting with n = m = c = 0
Not
The input will be terminated by a test case starting with n = m = c

Its stupid and ridicoulous how they make you print a blank line after last case.... in many problems with this blank line bullcrap, they give you W.A because you do print that last blank line, UVA judge should be modified to give presentation error on this kind of conditions, its annoying as hell

Fuse was blown.

Missing or extra newlines will usually result in WA, don't ever count on getting PE. Read the problem statement carefully. Output a blank line after each test case includes the last test case.

Help I got wrong answer

Code: Select all

got AC. Careless spelling mistake...

Help I got wrong answer

Change the spelling of

Squence

to

Sequence

on Line #39 and Line #43.

Code: Select all

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

int main(){
	long long n,m,c;
	int x=1;
	while(cin >> n >> m >> c){
		if(n==0 && m==0 && c==0){ cout << endl; break; }
		long long amp[n], op[m];
		bool swtch[n];
		memset(swtch, false, sizeof(swtch));
		for(int i = 1; i <= n; i++) cin >> amp[i];
		long long cons=0, max=0;
		for(int i = 0; i < m; i++) cin >> op[i];
		for(int i = 0; i < m; i++){
			if(swtch[op[i]] == false){
				swtch[op[i]] = true;
				cons += amp[op[i]];
				if(cons > max) max = cons;
			}
			else{
				swtch[op[i]] = false;
				cons -= amp[op[i]];
			}
		}
		if(cons <= c){
			cout << "Sequence " << x++ << endl;
			cout << "Fuse was not blown." << endl;
			cout << "Maximal power consumption was " << max << " amperes." << endl;
		}
		else{
			cout << "Sequence " << x++ << endl;
			cout << "Fuse was blown." << endl;
		}
		cout << endl;
	}
}

It gives me a wrong answer? Why is that?

You're printing two blank lines at the end of the output.

still getting WA. What could be the problem?

still getting WA. What could be the problem?

Try running your code at least once and consider looking at it objectively. This thread has some test cases. Check your code output against what's available on the forums.

So, you're no longer printing two lines at the end of the output but what do you think this line in your code is doing?

Code: Select all

 cout << "a" << endl;

It was for me to debug my code. I also tried all the test cases found in this forum. It outputs fine but still WA.

If you need help, post the exact code that's giving you a WA.
