### Re: 11926 - Multitasking

Hi, I've checked and passed all the previous test cases posted here, but I'm still getting WA Thanks for your help.

Code: Select all

``````#include <cstdio>
#include <cstdlib>
#include <iostream>
#include <cstring>
#define N 1000000
using namespace std;

int sched[1000010];

int main(void){
int n, m, s, e, p;
while(cin >> n >> m, n|m){
memset(sched, 0, sizeof sched);
bool conflict = false, processed = false;
for(int i=0; i<n; i++){
cin >> s >> e;
if(conflict) continue;
if(s+1<=N && sched[s+1] && e-s>1){conflict = true; continue;}
if(e-1>=0 && sched[e-1] && e-s>1){conflict = true; continue;}
if(e-s==1 && sched[s] && sched[e]){conflict = true; continue;}
if(e-s==0 && sched[s]){conflict = true; continue;}
for(int j=s; j<=e; j++)
if(j!=s && j!=e && sched[j])
{conflict = true; break;}
else sched[j] = 1;
}
if(conflict) {printf("CONFLICT\n"); processed = true;}
for(int i=0; i<m; i++){
cin >> s >> e >> p;
if(conflict) continue;
while(s <= 1000000){
if(s+1<=N && sched[s+1]){conflict = true; break;}
if(e-1>=0 && sched[e-1]){conflict = true; break;}
if(e-s==1 && sched[s] && sched[e]){conflict = true; break;}
if(e-s==0 && sched[s]){conflict = true; break;}
for(int j=s; j<=e; j++)
if(j!=s && j!=e && sched[j])
{conflict = true; break;}
else sched[j] = 1;
if(conflict) break;
s += p; e += p;
if(e>1000000) e=1000000;
}
}
if(conflict && !processed) printf("CONFLICT\n");
else if(!processed) printf("NO CONFLICT\n");
}
return 0;
}

### Re: 11926 - Multitasking

brianfry713, in the 24th test case you provided:

Code: Select all

``````0 1
5353 319104 794949
``````
I couldn't figure out why the AC output was "CONFLICT". If the period is 794949, I'd think that there's no conflict. Thank you very much for your answer

### Re: 11926 - Multitasking

I edited my previous post and corrected the I/O.
Input:

Code: Select all

``````1 1
999999 1000000
999998 999999 2
0 0

AC output: NO CONFLICT

### Re: 11926 - Multitasking

what is wrong with my code ?? I passed all test cases in this post and still getting WA

Code: Select all

``````#include<bits/stdc++.h>
using namespace std;

int n, m, a, b, c;
vector<pair<pair<int, int>, int> > arr;
char ans[][33] = { "CONFLICT", "NO CONFLICT" };
int test(int x, int y, int z, int g) {

return ((x > z && x < g) || (y > z && y < g) || (z > x && z < y)
|| (g > x && g < y) || (make_pair(x, y) == make_pair(z, g)));
}
int main(int argc, char **argv) {
#ifndef ONLINE_JUDGE
freopen("a.in", "r", stdin);
#endif
while (cin >> n >> m && (n + m)) {
arr.clear();
bool f = 1;
for (int i = 0; i < n; ++i) {
cin >> a >> b;
if(a > b)swap(a,b);
arr.push_back(make_pair(make_pair(a, b), 0));

}
for (int i = 0; i < m; ++i) {
cin >> a >> b >> c;
if(a > b)swap(a,b);
arr.push_back(make_pair(make_pair(a, b), c));
if (b - a > c && !c)
f = 0;
}
for (size_t i = 0; i < arr.size(); ++i) {
for (size_t j = 0; j < arr.size(); ++j) {
if (i == j)
continue;
int x = arr[i].first.first, y = arr[i].first.second, cst =
arr[i].second;
while (x <= arr[j].first.second) {
if (test(x, y, arr[j].first.first, arr[j].first.second)) {
f = 0;
break;
}
if (!cst)
break;
x += cst;
y += cst;
}
}
}
cout << ans[f] << endl;
}
return 0;
}

It looks like you figured it out.
