So count (key) returns the number of elements of the key, and find (key) returns the first function of the key.Here is a simple example of applying a map container: Reading a file, recording the number of occurrences of each word in the file, and outputting the occurrences of the word and the number of occurrences in dictionar

One1. Features(1) The quicksort algorithm ' s desirable features is, it's in-place (uses only a small auxiliary stack) and thatIt requires time proportional to n log n on the average to sort an array of length N.(2) quicksort have a shorter inner loop than most other sorting algorithms, which means that it's fast in practice as well as in theory.2. Disadvantages:(1) Its primary drawback are that it's fragile in the sense that some care are involved in
