Java基础(快速排序算法)

基本思想任取待排序元素序列中的某元素作为基准值，按照该排序码将待排序集合分割成两子序列，左子序列中所有元素均小于基准值，右子序列中所有元素均大于基准值，然后最左右子序列重复该过程，直到所有元素都排列在相应位置上为止。具体方法选择一个基准元素，通常选择第一个元素或者最后一个元素, 通过一趟排序将...

Java入门高频考查算法逻辑基础知识3-编程篇（超详细18题1.8万字参考编程实现）

准备这些面试题时，请考虑如下准备步骤：理解问题并澄清任何可能的疑点。确保你了解了面试官的期望，包括问题限制条件和期望的解决方案。如果可能且适用的话，尝试先给出一个简单的解决方案，比如暴力法，然后再逐步优化它。在优化之前，先分析暴力解法的效率，了解它的时间和空间复杂度，然后解释为什么需要更有效的...
