algorithm Counting Sort Psuedocode Implementation



  1. Input (an array to be sorted)
  2. Number of element in input (n)
  3. Keys in the range of 0..k-1 (k)
  4. Count (an array of number)


for x in input:
    count[key(x)] += 1
total = 0
for i in range(k):
    oldCount = count[i]
    count[i] = total
    total += oldCount
for x in input:
    output[count[key(x)]] = x
    count[key(x)] += 1
return output
