The main idea is given a string of 1 to n arrangement (set to an array of a), which satisfies a[x]The number of such permutations is not so good that we can convert to the number of a[x]Using the left array to record the number of elements that are smaller than a[i] before the position of I, then we can get the formula for the number of permutations (see Code), which can be preprocessed by a tree array.#include HDU 4000 Fruit Ninja (tree-like arra
