Insert Sorting works possibly the fastest way If we don't know how sorted our array is. You need to specify a table, and the table's index which we will be using to sort with. For Example if our table has values like this, then you would specify 3: {player, vehicle, playerid, npc} local table = insertSortingByIndex(table, 3)

```function insertSortingByIndex(array, e)
local data = array
for i = 2, #data do
local j = i - 1
local ass = data[i]
while j > 0 and data[j][e] > ass[e] do
data[j + 1] = data[j]
j = j - 1
end
data[j + 1] = ass
end
return data
end
```

o(n^2) Sorting algorithm for lua.

```function fixedBubbleSortingByIndex(array, e)
local data = array
local i = #data
while i >= 2 do
local idx = 0
for j = 1, (i - 1) do
if data[j][e] > data[j + 1][e] then
local holder = data[j][e]
data[j][e] = data[j + 1][e]
data[j + 1][e] = holder
idx = j
end
end
i = idx
end
return data
end
```

## Usage

```local TestArray = {
{1, "test"},
{33, "test"},
{-32, "test"},
{-1, "test"},
{5, "test"},
{11, "test"},
{968, "test"},
{723, "test"},
{33, "test"},
{16, "test"},
{4, "test"},
{5, "test"},
}
local SortedTestArray = fixedBubbleSortingByIndex(TestArray, 1)
for k, v in pairs(SortedTestArray) do
outputChatBox("Value: " .. v[1])
end
local SortedTestArray2 = insertSortingByIndex(TestArray, 1)
for k, v in pairs(SortedTestArray2) do
outputChatBox("Value: " .. v[1])
end
```
