488 - Triangle Wave

[Schutzstaffel]

This is weird, the main change you did was to not test when it was the last wave and print the newline anyway (I kept the the multiple inputs) and of course to simplify the code that was really messy lol but the thing is I had outputs that were equals to the now AC code I thought maybe it would be because I tested if frequency and amplitute were 0 but I also tried without that.
Oh well it's AC now, thanks for your help and for everyone else who replied.

this program seems t conform to all the rules but still gets PE! help!

Code: Select all

#include <iostream>

using namespace std;

int main()
{
    short a = 0;
    short f = 0;
    short n = 0;
    
    cin >> n;
    
    while(n)
    {
        cin >> a;
        cin >> f;
    
        for(char i = 1; i <= f; i++)
        {
            for(char j = 1; j <= a; j++)
            {
                for(char k = 1; k <= j; k++)
                    cout << (int)j;
                if(a != 1)
                    cout << endl;
            }
            for(char j = a - 1; j >= 1; j--)
            {
                for(char k = 1; k <= j; k++)
                    cout << (int)j;
                cout << endl;
            }
            if(!(i == f && n == 1))
                cout << endl;
        }
        n--;
    }
    
    return 0;
}

Check the output description:

The outputs of two consecutive cases will be separated by a blank line.

NOTE: There is a blank line after each separate waveform, excluding the last one

Remove your code after you get AC.

Input:

Output:

333\n

Should I remove the last '\n' ?

Nope. In fact this is ok. Apparently I overlooked one line of code in your program which does this. But then again to get AC you have to print a blank line after each triangle wave, which is exactly what my AC program (no PE) did. I know what my AC program did does not really conform to the output description. I will leave a post in the Bugs and Suggestions forum regarding this.

I don't get it! Now i'm getting WA!!!

Code: Select all

#include <iostream>

using namespace std;

int main()
{
    short a = 0;
    short f = 0;
    short n = 0;
    
    cin >> n;
    
    while(n)
    {
        cin >> a;
        cin >> f;
    
        for(char i = 1; i <= f; i++)
        {
            for(char j = 1; j <= a; j++)
            {
                for(char k = 1; k <= j; k++)
                    cout << (int)j;
                cout << endl;
            }
            for(char j = a - 1; j >= 1; j--)
            {
                for(char k = 1; k <= j; k++)
                    cout << (int)j;
                cout << endl;
            }
            if(!(i == f && n == 1))
                cout << endl;
        }
        n--;
    }
    
    return 0;
}

Code: Select all

code is deleted after AC

tankyou very much for the example i got AC.

How this solution can give P.E I cannot imagine that's about 488, the assumed easiest problem. What's wrong with this? Plz help anyone. Plz check out the output first for my solution.
Hope to hear from you soon.

Code: Select all

#include<stdio.h>

main() {
 printf("Code removed after AC.\n");
 return 0;
}

[helloneo]

Search first..
Don't open a new thread if there is one already..

[linux]

Thanks everyone! The problem was for multiple cases! I got it and got AC.


I opened this thread because old threads weren't enough to recognise the problem! Good luck.

[newton]

Mr LINUX.


you must delete your code after AC. Otherwise another person may copy and paste it.





best of luck.

[helloneo]

Days have changed Newton! If you don't believe try the code to get AC.
I recommend it's impossible for you. Because days have changed. Try out... http://acm.uva.es/problemset/author.html[/b]

No.. what newton mean is your code could be a spolier..
In this forum, we remove our code after getting AC..
And another thing, if there is a thread already, we don't open a new thread.. just using old thread to post..

[newton]

thanx.
