This algorithm is a combination of radix sort and quicksort. Pick an element from the array (the pivot) and consider the first character (key) of the string (multikey). Partition the remaining elements into three sets: those whose corresponding character is less than, equal to, and greater...
A(m, n) = m! / (m - n)! ---> 排列 ---> permutation C(m, n) = m! / n! / (m - n)! ---> 组合 ---> combination 如:C(5, 3) = 5! / 3! / 2! = 10 实现: m = int(input('m = ')) n = int(input('n = ')) ...
