不管是while循环还是for循环,原理都是取根号,循环到取根号后的数,至于为什么需要循环到开根后的数,我想主要是因为一个数的分解因子在开根号后的数向上取整以下吧. 话不多说,上代码: while循环: while循环原理如下: i = 2 while i <= 100: # 内层循环 j 从2循环到根号 i j = 2 while j <= (i / j): # j <= (i/j) 等效于 j*j <= i 也就等于 j <= 根号 i if i % j == 0: br
1147 Heaps (30 分) In computer science, a heap is a specialized tree-based data structure that satisfies the heap property: if P is a parent node of C, then the key (the value) of P is either greater than or equal to (in a max heap) or less than or
