Find the sum of all the multiples of 3 or 5 below 1000 题解 初步解 题目需要我们求小于1000的数中,3的倍数和5的倍数的总和。最简单的思路就是枚举:枚举每一个数字,判断其是否是3的倍数或5的倍数,如果是,那就加上;如果不是那就不管。 checkAndReturn::Integer->IntegercheckAndReturnn=ifremn3==0||...
Multiples of 3 and 5 原题 题意如下: 找出N以内的3和5的倍数的和。 思路 1、刚看到觉得好弱智,直接遍历一遍不就OK了吗?但是第2和第3个测试用例报了TLE,超时。 2、然后想不出来了,搜了一下,发现有一个类似的题计算1000以内的3和5的倍数的和,用的是算出3的倍数的和加上5的倍数的和减去15的倍数的和...
如果我们将小于10的所有是3或5倍数的自然数列出来,我们得到3,5,6和9,它们的和是23。与之类似,计算1000以下所有是3或5的倍数的自然数的和。 分析:此题至少有两种解法,第一种解法较为直接,将1000以下所有3或5的倍数列出再求即可,在python中使用列表推导式只需要一行代码即可。第二种思路是使用求和公式,分别求...
sum5ofn = 5 * (1 + n / 5) * (n / 5) / 2 当结过并不是sum3ofn + sum5ofn。 对比两个数列可以发现,能15整除的数在两个数列里都出现了,所以正确的结果应该为: sum3ofn + sum5ofn - sum15ofn 代码如下: 1#promble 1: Multiples of 3 and 52#计算小于target,且能被n整除的数之和3def...
