传送门:>Here< 题目大意:先抛出了一个问题——“已知一个序列,将此序列中的元素划分成几组(不需要连续)使得每一组中的任意两个数的乘积都是完全平方数.特殊的,一个数可以为一组.先要求最少分几组.”在这个问题的基础上,给出一个长度为n的序列,该序列有\(\frac{n(n+1)}{2}\)个子序列,求每个子序列对于上面这个问题最少划分几次.并分别统计最少划分k次的子序列有几个. 解题思路 题目由于是英文的,好长时间没读懂,而且还读错.注意he needs to find the number…

Given a positive integer num, write a function which returns True if num is a perfect square else False. Note: Do not use any built-in library function such as sqrt. Example 1: Input: 16 Returns: True Example 2: Input: 14 Returns: False Credits:Speci…
Given a positive integer n, find the least number of perfect square numbers (for example, 1, 4, 9, 16, ...) which sum to n. For example, given n = 12, return 3 because 12 = 4 + 4 + 4; given n = 13, return 2 because 13 = 4 + 9. Credits:Special thanks…
