Binary Search 是一种用于搜索已排序列表中元素的技术。在本文中,我们将研究执行Binary Search 的库函数。 1.查找元素的首次出现 bisect.bisect_left(a,x,lo = 0,hi = len(a)):返回排序列表中x的最左插入点。最后两个参数是可选的,它们用于在子列表中搜索。 # Python code to demonstrate working # of ...

上一篇的递归算法中,了解到算法的复杂度。递归就是在函数中调用本身。 在汉诺塔游戏例子中,如果你需要移动的盘子很多时,程序运行就会消耗很长时间来计算结果。可以回顾下 —>算法篇-python递归算法 用递归打印斐波那契数列,你会发现,即使n只有几十的时候,你的计算机内存使用量已经飙升了。
