Bubble Sort

Bubble sort code

func Sort(arr []int) []int {
	for i := 0; i < len(arr)-1; i++ {
		for j := 0; j < len(arr)-i-1; j++ {
			if arr[j] > arr[j+1] {
				temp := arr[j]
				arr[j] = arr[j+1]
				arr[j+1] = temp
			}
		}
	}
	return arr
}

BubbleSort

const bubbleSort = (arr) => {
  let temp = 0;
  for (let i = 0; i < arr.length; i++) {
    for (let j = 1; j < arr.length; j++) {
      if (arr[j - 1] > arr[i]) {
        temp = arr[j - 1];
        arr[j - 1] = arr[i];
        arr[i] = temp;
      }
    }
  }
  return arr;
};

console.log(bubbleSort([10, 9, 8, 7, 6, 5, 4, 3, 2, 1]));

Algorithm of bubble sort

begin BubbleSort(list)

   for all elements of list
      if list[i] > list[i+1]
         swap(list[i], list[i+1])
      end if
   end for
   
   return list
   
end BubbleSort
