An example of using Python to implement the principles of radix sorting algorithm
Jan 22, 2024 pm 01:36 PMThe radix sorting algorithm is a type of bucket sorting algorithm, which sorts values based on the same position into groups. Maybe it's a bit hard to understand. You can look at the following example of the principle of radix sorting algorithm.
Principle example of radix sort algorithm
Specify the array [121,432,564,23,1,45,788], and sort the array by radix, as shown in the figure:

#First sort the single-digit values, then sort the tens-digit values, and finally sort the hundreds-digit values, and finally output the sorted The array is [001,023,045,121,432,564,788]
Python code to implement the radix sorting algorithm
def countingSort(array, place): size = len(array) output = [0] * size count = [0] * 10 for i in range(0, size): index = array[i] // place count[index % 10] += 1 for i in range(1, 10): count[i] += count[i - 1] i = size - 1 while i >= 0: index = array[i] // place output[count[index % 10] - 1] = array[i] count[index % 10] -= 1 i -= 1 for i in range(0, size): array[i] = output[i] def radixSort(array): # Get maximum element max_element = max(array) place = 1 while max_element // place > 0: countingSort(array, place) place *= 10 data = [121, 432, 564, 23, 1, 45, 788] radixSort(data) print(data)
