剑指Offer--美团内推+校招笔试题+知识点总结 前言 美团9.9内推笔试.9.11校招笔试,反正就是各种虐,笔试内容如下: 知识点:图的遍历(DFS.BFS).进程间通信.二叉查找树节点的删除及中序遍历.HTTP会话的4个过程.红黑树.1024!有多少个0,60块糖分给5个人,如何分等.编程题考察拿红包.多叉树(见下图). 另外,更变态的是其IDE编程居然在多行输入问题上死翘翘了,基本上就是纠结于到底如何实现多行输入,结果就挂了!整理后的多行输入如下: package cn.edu.ujn.…
1 有一个函数, 写一段程序,输入的值,输出的值. #include <stdio.h> void main() { int x,y; printf("输入x:"); scanf("%d",&x); if(x<0||x>100) /* x<0或x>100*/ { y=-1; printf("x=%3d, y=%d\n" ,x,y); } else if(x==0) /* x=0*/ { y=0; pri…
