Hi,
I am participating for the code jam 2019 for first time and for practice I have
solved the 2018 qualification round 'Saving the Universe again' problem using
C#. and I am getting the correct outputs. But when i submit the problem, its
showing wrong answer. I dont know what else do i need to add the code as there
are few hours left to begin the competitions.
Can you please help what is wrong?. Here is my raw code.
using System;
namespace ConsoleApp1
{
class Program
{
static void Main()
{
//BasicTest();- 1
var T = int.Parse(Console.ReadLine());
for (int i = 0; i < T; i++)
{
var DP = Console.ReadLine();
var splitDP = DP.Split(' ');
var D = int.Parse(splitDP[0]);
var P = splitDP[1];
var mH = 0;
var b = 1;
var s =0;
var c = 0;
int sum = 0;
var nP = string.Empty;
var sC = P.Replace("c", "").Length;
if (sC > D)
{
Console.WriteLine("Case #" + (i + 1) + ": " + "IMPOSSIBLE");
continue;
}
if (!P.Contains("c"))
{
Console.WriteLine("Case #" + (i + 1) + ": " + mH);
}
else
{
sum=CountSum(P,s,b,c,sum);
while(sum>D)
{
mH++;
var temp = P.IndexOf("cs");
var subP = P.Substring(temp, 2);
var arr = subP.ToCharArray();
Array.Reverse(arr);
subP = new string(arr);
P =P.Substring(0,temp)+ subP+ P.Substring(temp+2,
P.Length-(temp + 2));
sum=CountSum(P, 0, 1, 0, 0);
}
Console.WriteLine("Case #" + (i + 1) + ": " + mH);
}
}
Console.ReadLine();
}
public static int CountSum(string P, int s, int b, int c, int sum)
{
for (int j = 0; j < P.Length; j++)
{
if (P[j] == 's')
{
s = b;
b = s;
sum = sum + s;
}
else
{
c = 2 * b;
b = c;
}
}
return sum;
}
//public static void BasicTest()
//{
// var T = int.Parse(Console.ReadLine());
// for (int t = 0; t < T; t++)
// {
// var N = int.Parse(Console.ReadLine());
// var Arr = Console.ReadLine();
// var X = Console.ReadLine();
// if (!Arr.Contains(X))
// Console.WriteLine("-1");
// var strArr = Arr.Split(' ');
// findElement(strArr, X);
// }
// Console.ReadKey();
//}
//public static void findElement(string[] strArr, string X)
//{
// Console.WriteLine(Array.IndexOf(strArr, X, 0));
//}
}
}
