Question

You will be given N – an integer specifying the length of an array. Then you will start receiving an index and a value. For each received line you must set the value at the given index to the given value. When you’ve processed all input data, print the array’s elements each on a new line.

Examples:

Input	Output		Input	Output		Input	Output
3 0 - 5 1 – 6 2 – 7	5 6 7		2 0 – 5 0 – 6 0 – 7	7 0		5 0 – 3 3 - -1 4 – 2	3 0 0 -1 2

 

Answer 1

Here is the answer:

function set(arr) {
  let count = parseInt(arr[0]);
  let numbers = [];//New array

  for (let i = 0; i < count; i++) {
    numbers[i] = 0;
  }

  for (var i = 1; i < arr.length; i++) {
    let pair = arr[i].split(' - ').map(Number);
    let index = parseInt(pair[0]);
    let value = parseInt(pair[1]);

    numbers[index] = value;
  }
  console.log(numbers.join('\n'));
}

// set('3',
//   ['0 - 5',
//     '1 - 6',
//     '2 - 7']
// );
