Array modifier

Здравейте,

Не си виждам грешката, а judge не ми дава никакви точки. Нулевите тестове минават.

You are given an array with integers. Write a program to modify the elements after receiving the following commands:

takes two elements and swap their places.
takes element at the 1st index and multiply it with the element at 2nd index. Save the product at the 1st index.
decreases all elements in the array with 1.

Input

On the first input line, you will be given the initial array values separated by a single space.

On the next lines you will receive commands until you receive the command "end". The commands are as follow:

Output

The output should be printed on the console and consist of elements of the modified array – separated by a comma and a single space ", ".

Constraints

Elements of the array will be integer numbers in the range [-231...231]
Count of the array elements will be in the range [2...100]
Indexes will be always in the range of the array

23 -2 321 87 42 90 -123

swap 1 3

swap 3 6

swap 1 0

multiply 1 2

multiply 2 1

decrease

end

86, 7382, 2369942, -124, 41, 89, -3

23 -2 321 87 42 90 -123 – initial values

swap 1(-2) and 3(87) ▼

23 87 321 -2 42 90 -123

swap 3(-2) and 6(-123) ▼

23 87 321 -123 42 90 -2

swap 1(87) and 0(23) ▼

87 23 321 -123 42 90 -2

multiply 1(23) 2(321) = 7383 ▼

87 7383 321 -123 42 290 -2

multiply 2(321) 1(7383) = 2369943 ▼

87 7383 2369943 -123 42 90 -2

decrease – all - 1 ▼

86 7383 2369942 -124 41 89 -3

1 2 3 4

swap 0 1

swap 1 2

swap 2 3

multiply 1 2

decrease

Best Answer

"decrease" decreases all elements in the array with 1.

;-)

function solve(input) {
    // Parse all values in the array to int values
    let initialArray = input[0]
    .split(' ')
    .map(Number);

    for (let i = 1; i < input.length; i++) {

        let [command, index1, index2] = input[i].split(' ');

        // Values need to be parsed from string to int
        index1 = Number(index1);
        index2 = Number(index2);

        if (command === 'swap') {
            let first = initialArray[index1];
            let second = initialArray[index2];
            initialArray[index1] = second;
            initialArray[index2] = first;
        }
        if (command === 'multiply') {
            let first = initialArray[index1];
            let second = initialArray[index2];
            initialArray[index1] = first * second;
        }
        if (command === 'decrease') {
            initialArray = initialArray.map(el => el - 1);

            // ERROR
            // Carefull !!! .join will transform array into a string
            // initialArray = initialArray.map(el => el - 1).join(', ');
        }
    }

    // console.log(initialArray)
    return initialArray.join(', ');
}

Дам, добре е конвертирането на данните да се случва в началото :Д

Едно решение за C#

int[] numbers = Console.ReadLine().Split(" ", StringSplitOptions.RemoveEmptyEntries).Select(int.Parse).ToArray();

string command = Console.ReadLine();

while (command != "end")
{
string[] commandInfo = command.Split(" ");
string action = commandInfo[0];

if (action == "swap")
{
int index1 = int.Parse(commandInfo[1]);
int index2 = int.Parse(commandInfo[2]);
int first = numbers[index1];
int second = numbers[index2];
numbers[index1] = second;
numbers[index2] = first;

}

else if (action == "multiply")
{
int index1 = int.Parse(commandInfo[1]);
int index2 = int.Parse(commandInfo[2]);
int first = numbers[index1];
int second = numbers[index2];
numbers[index1] = first * second;

}
else if ( action == "decrease")
{
for (int i = 0; i < numbers.Length; i++)
{
numbers[i] -= 1;
}
}

command = Console.ReadLine();
}

Console.WriteLine(string.Join(", ", numbers));
