1.- Insert:
mark first element as sorted
for each unsorted element
'extract' the element
for i = lastSortedIndex to 0
if currentSortedElement > extractedElement
move sorted element to the right by 1
else: insert extracted element
2.- Select:
repeat (numOfElements - 1) times
set the first unsorted element as the minimum
for each of the unsorted elements
if element < currentMinimum
set element as new minimum
swap minimum with first unsorted position
3.- Bubble:
do
swapped = false
for i = 1 to indexOfLastUnsortedElement
if leftElement > rightElement
swap(leftElement, rightElement)
swapped = true
while swapped
# Start with the largest gap and work down to a gap of 1
foreach (gap in gaps){
# Do a gapped insertion sort for this gap size.# The first gap elements a[0..gap-1] are already in gapped order
# keep adding one more element until the entire array is gap sorted
for (i = gap; i < n; i += 1){
temp = a[i]
for (j = i; j >= gap and a[j - gap] > temp; j -= gap){
a[j] = a[j - gap]
}
a[j] = temp
}
}
split each element into partitions of size 1
recursively merge adjancent partitions
for i = leftPartStartIndex to rightPartLastIndex inclusive
if leftPartHeadValue <= rightPartHeadValue
copy leftPartHeadValue
else: copy rightPartHeadValue
copy elements back to original array
7.- Quick:
for each (unsorted) partition
set first element as pivot
storeIndex = pivotIndex + 1
for i = pivotIndex + 1 to rightmostIndex
if element[i] < element[pivot]
swap(i, storeIndex); storeIndex++
swap(pivot, storeIndex - 1)
