Passo 22

Instruções

Registre a string 'Unsorted array: ' no console.

O que fazer:

Testes:

Você deve registrar a string especificada usando `console.log('Unsorted array: ')`.

function mergeSort(array) {
  if (array.length <= 1) {
    return;
  }

  const middlePoint = Math.floor(array.length / 2);
  const leftPart = array.slice(0, middlePoint);
  const rightPart = array.slice(middlePoint);
  
  mergeSort(leftPart);
  mergeSort(rightPart);
  
  let leftArrayIndex = 0;
  let rightArrayIndex = 0;
  let sortedIndex = 0;
  
  while (leftArrayIndex < leftPart.length && rightArrayIndex < rightPart.length) {
    if (leftPart[leftArrayIndex] < rightPart[rightArrayIndex]) {
      array[sortedIndex] = leftPart[leftArrayIndex];
      leftArrayIndex += 1;
    } else {
      array[sortedIndex] = rightPart[rightArrayIndex];
      rightArrayIndex += 1;
    }
    sortedIndex += 1;
  }

  while (leftArrayIndex < leftPart.length) {
    array[sortedIndex] = leftPart[leftArrayIndex];
    leftArrayIndex += 1;
    sortedIndex += 1;
  }

  while (rightArrayIndex < rightPart.length) {
    array[sortedIndex] = rightPart[rightArrayIndex];
    rightArrayIndex += 1;
    sortedIndex += 1;
  }
}

const numbers = [4, 10, 6, 14, 2, 1, 8, 5];
