C# - Exercises: Data Types and Variables - 11.SnowBalls - 90/100

Здравейте колефи,

Може ли малко помощ със следната задача:

Tony and Andi love playing in the snow and having snowball fights, but they always argue which makes the best snowballs. Because they are girls (which means they are completely illogical), they have decided to involve you in their fray, by making you write a program which calculates snowball data, and outputs the best snowball value.

You will receive N – an integer, the number of snowballs being made by Tony and Andi.
For each snowball you will receive 3 input lines:

On the first line you will get the snowballSnow – an integer.
On the second line you will get the snowballTime – an integer.
On the third line you will get the snowballQuality – an integer.

For each snowball you must calculate its snowballValue by the following formula:

(snowballSnow / snowballTime) ^ snowballQuality

At the end you must print the highest calculated snowballValue.

Input

On the first input line you will receive N – the number of snowballs.
On the next N * 3 input lines you will be receiving data about snowballs.

Output

As output you must print the highest calculated snowballValue, by the formula, specified above.
The output format is:
{snowballSnow} : {snowballTime} = {snowballValue} ({snowballQuality})

Constraints

The number of snowballs (N) will be an integer in range [0, 100].
The snowballSnow is an integer in range [0, 1000].
The snowballTime is an integer in range [1, 500].
The snowballQuality is an integer in range [0, 100].

Allowed working time / memory: 100ms / 16MB.

Examples

Input

Output

10 : 2 = 125 (3)

10 : 5 = 128 (7)

Ето и моя код: https://pastebin.com/6bdH35sx

Judge дава 90/100 и не мога да си намеря грашката.Всички проверки излизат.

Здравей,

Не съм от C#, но това за което се сещам е да пробваш на ред 21 с >= . Също може би изход при вход 0

using System;
using System.Numerics;

namespace Snowballs
{
class Program
{
static void Main(string[] args)
{
int n = int.Parse(Console.ReadLine());
BigInteger maxValue = 0;
string bestResult = "";
for (int i = 0; i < n; i++)
{
int snowBalls = int.Parse(Console.ReadLine());
int snowBallTime = int.Parse(Console.ReadLine());
int snowBallQuality = int.Parse(Console.ReadLine());
BigInteger value= BigInteger.Pow((snowBalls / snowBallTime) , snowBallQuality);
if (value >= maxValue)
{
maxValue = value;
string result = ($"{snowBalls} : {snowBallTime} = {maxValue} ({snowBallQuality})");
bestResult = result;
}
}
Console.WriteLine(bestResult);
}
}
}

Ето и моето решение - 100/100.

@Dani77

Mersi Dani, i az imah 90/100 no kato izpolzvah tvoqta logika za BigInteger mi dade 100/100.

Zashto mislish BigInteger raboti a kogato raboteh s double mi davashe greshka. Eto i dvata koda za sravnenie:

Да, вкарах BigInteger в задачата и илзезе 100/100.Използвах го също вместо Math.Pow / BigInteger.Pow
