题目:输入n个整数,找出其中最小的k个数。
《剑指offer》给出了两种实现算法:
算法1:采用Partition加递归法,该算法可以说是快速排序和二分查找的有机结合。算法的时间复杂度为O(n),缺点在于在修改Partition的过程中会修改原数组的值。
算法2:采用top-k算法。如果要找最小的K个数,我们才用一个含有K个值的大顶堆;如果要找最大的K个数,我们采用小顶堆。该算法的时间复杂度为O(nlogK),是一种比较好的算法,启发于堆排序。...

题目来源:剑指offer之寻找丑数 与 待字闺中之序列生成分析
两个题目其实是同一个问题,所有放在一起,算是总结一下,题目如下:
给定一个表达式2^i*2^j,其中i,j为非负整数。请找到一种方法,生成如下序列:
2^0 * 5^0 = 1
2^1 * 5^0 = 2
2^2 * 5^0 = 4
2^0 * 5^1 = 5
2^3 * 5^0 = 8
2^1 * 5^1 = 10
2...
