Nice problem with ugly dataset. You need extra spaces in two aspects to avoid PE.
1.Print an extra space after the string "no concurrent events."
2.Print an extra space after each pair of concurrent events (both one pair and two pairs)

After Getting More PE ..finally Got It Accepted..... :D
What I did is
You just have to print an extra space after each pair of concurrent events.Look at the example(Lets denote space as 'X')

Code: Select all

CaseX1,X2XconcurrentXevents:
(e1,e4)X(e2,e4)X 
CaseX3,XnoXconcurrentXevents.
CaseX4,X1XconcurrentXevents:
(alpha,gamma)X

I have followed the advice in this thread, but I would still get PE. However, if I don't put a "\n" after the last testcase, I receive WA. I suspect it's supposed to be PE again. Can someone take a look at my code and tell me if there's anything strange? Thanks in advance!

Code: Select all

#include <cstdio>
#include <cstring>
#include <string>
#include <map>
#include <iostream>
#define pii pair <int, int>
#define x first
#define y second
#define mp make_pair
#define NMAX 205
using namespace std;
string curr, words[NMAX];

int main()

    int i, j, k, no, x, y, test_no = 0;
    while (scanf("%d", &n), n)
    {
        test_no++;
        if (test_no > 1)
            cout << "\n";
            
        for (i = 1; i <= n; i++)
        {
            scanf("%d", &no);
            if (no)
            {

Put a newline at the end of the last line.
Here is the correct sample output if you delete everything in between [ and ], note where the trailing spaces are and are not.

Code: Select all

Case 1, 2 concurrent events:[no trailing space]
(e1,e4) (e2,e4) [trailing space]
Case 2, 10 concurrent events:[no trailing space]
(two,four) (two,five) [trailing space]
Case 3, no concurrent events.[no trailing space]
Case 4, 1 concurrent events:[no trailing space]
(alpha,gamma) [trailing space]

I followed the advice and generate the right output

Code: Select all

Case 1, 2 concurrent events:
(e1,e4) (e2,e4)_
Case 2, 10 concurrent events:
(two,four) (two,five)_
Case 3, no concurrent events.
Case 4, 1 concurrent events:
(alpha,gamma)_

However I still got PE, does anybody know why?
Then I tried all the combinations of (all 8 combinations = 2^3)
1. space after "concurrent events:X" or not
2. space after "no concurrent events.X" or not
3. space after pairs like "(e2,e4)X" or not
but all PE...
