Given a positive integer n, find the least number of perfect square numbers (forexample,1,4,9,16, ...) which sum to n. For example, given n=12,return3because12=4+4+4; given n =13,return2because13=4+9. 二、中文讲解 1、这道题说是给我们一个正整数,求它最少能由几个完全平方数...
python3cppjava 做法1: 算法:dp 我们用f[i]表示i最少能被几个完全平方数来表示。 首先我们对dp数组赋予初值,对于每个完全平方数的f=1。 利用记忆化搜索来完成查找。对于i,我们考虑i的前继状态,也就是哪几个状态可以加上一个完全平方数抵达i。
