Insert sort directly: Algorithm idea: 1. The array is divided into two parts: ordered part and unordered part 2. Divide the initial data into ordered parts and unordered parts. In each step, insert the data of an unordered part into the ordered part that has been arranged previously And so on until all elements are sorted Average time complexit ...

Algorithm idea: Starting from the first element, compare the values of two adjacent elements in pairs, and put the larger one behind (from small to large) Average time complexity: O(n2) Worst time complexity: O(n2) Optimal time complexity: O(n) Space complexity: 1 Stability: unstable Suitable for scene: few elements Code implementation: Mode 1 ...

Bubble sorting Step analysis and introduction As can be seen from the figure below, when comparing two adjacent elements, the large number will move backward (how to move it later?), so after each comparison, a larger number will be placed at the end, and the last number does not need to be compared, that is, after each comparison, the ...
