Not sure what's causing it.


#include <iostream>
#include <vector>
#include <string>
using namespace std;

const int show[10][7] =
{
/*0*/ {1,1,1,1,1,1,0,},
/*1*/ {0,1,1,0,0,0,0,},
/*2*/ {1,1,0,1,1,0,1,},
/*3*/ {1,1,1,1,0,0,1,},
/*4*/ {0,1,1,0,0,1,1,},
/*5*/ {1,0,1,1,0,1,1,},
/*6*/ {1,0,1,1,1,1,1 ...

I fixed the problem. AC.

Okay I changed it once again using a recursive function. It runs much faster, fast enough I believe but I get a "Runtime Error (SIGSEGV)" for some reason I can't think of....

#include <iostream>
#include <vector>
#include <string>
using namespace std;

void print(vector<char> & sequence)
{
for ...

I made a few alterations an it is faster but I still get Time Limit Exceeded.
If the lengths of the original and objective word is different it prints nothing, if the words do not contain the same letters it terminates, otherwise it goes through all the combinations of valid pushes and pops until ...

I start from "i i ......i" 2n n times where n is the length of the word and increase it one by one, i.e. "i i i i i i i" "i i i i i i o" "i i i i i o i" "i i i i i o o" to check to see if they are valid. Is there a faster way?

#include <iostream>

There won't be negative numbers inputted would there? I thought Smith numbers were only positive. So why would that matter?

I'm getting a wrong answer and I have no idea why. I know it's multiple output and my answers look fine when I try them. Any ideas?

#include <iostream>
using namespace std;

void line(int number)
{
int times = 0;
do {
cout << number;
times++;
} while (times<number);
}

int main()
{
int amp ...

I just realized my solutions for "# 1" are incorrect.

I've tried all the sample tests I could find and every one of them produce the correct answer but I'm still getting a WA. Any suggestions? Here is my code:


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

void main()
{
int i, w, n, h, hc;
int height = 1, workers=1;


cin >> i >> w ...

Hmmm, that would explain it but it still seems strange. If a plane was travelling "south" and the wind direction was "north", I would think the wind was moving in the opposite direction of the plane. Oh well.

I solved this problem and it was accepted except I had to make it output what I think is the wrong answer.

WIND SPEED 15.00
WIND DIRECTION 290.00
DESIRED COURSE 260.00
TRUE AIRSPEED 100.00
AIRCRAFT HEADING 264.30
GROUND SPEED 86.73

Looking at that example, it says the wind is moving at 290 degrees ...
