题目链接 描述 Dr.Kong设计的机器人卡多掌握了加减法运算以后,最近又学会了一些简单的函数求值,比如,它知道函数min(20,23)的值是20 ,add(10,98) 的值是108等等.经过训练,Dr.Kong设计的机器人卡多甚至会计算一种嵌套的更复杂的表达式. 假设表达式可以简单定义为: 1. 一个正的十进制数 x 是一个表达式. 2. 如果 x 和 y 是 表达式,则 函数min(x,y )也是表达式,其值为x,y 中的最小数. 3. 如果 x 和 y 是 表达式,则 函数max(x,y…

题目链接 描述 ACM队的mdd想做一个计算器,但是,他要做的不仅仅是一计算一个A+B的计算器,他想实现随便输入一个表达式都能求出它的值的计算器,现在请你帮助他来实现这个计算器吧. 比如输入:"1+2/4=",程序就输出1.50(结果保留两位小数) 输入 第一行输入一个整数n,共有n组测试数据(n<10).每组测试数据只有一行,是一个长度不超过1000的字符串,表示这个运算式,每个运算式都是以"="结束.这个表达式里只包含+-*/与小括号这几种符号.其中小括号…

Given a tree, you are supposed to tell if it is a complete binary tree. Input Specification: Each input file contains one test case. For each case, the first line gives a positive integer N (≤20) which is the total number of nodes in the tree -- and…

Excel can sort records according to any column. Now you are supposed to imitate this function. Input Specification: Each input file contains one test case. For each case, the first line contains two integers N (≤10​5​​) and C, where N is the number o…
