3.3 The Five-Number Summary; Boxplots the deciles divide a data set into tenths (10 equal parts), the quintiles divide a data set into fififths (5 equal parts), and the quartiles divide a data set into quarters (4 equal parts). an extreme observation
1. 数值比较 -eq 是否相等(equal) -gt 是否大于(greater than) -ge 是否大于等于(greater and equal than) 同理小于等于(le),小于(lt) less -ne 是否不等于(not equal) 1 #测试变量1是否大于等于22 if [ $1 -ge "2" ]; then3 echo yes!

如下代码,对于两个局部数组遍历s1和s2,其中s1的大小为4,而字符串“test”在给其赋值时,将导致最后的结束符赋值到紧随其后的s2数组的开始。而后,在数组s2赋值时,第二个字符串“test”的第一个字符t由将覆盖之前的结束符。 #include <stdio.h> #include <string.h> int main() {
Check Palindrome or Not in C++ To check for palindrome i.e., whether entered number is palindrome or not in C++ programming, you have to first ask from the user to enter a number. Now to check whether the entered number is a palindrome number (if reverse
给你一个n长度的数组,让你修改0到n次,问每次修改后能剩下不同个数的最小数是多少; 这里有了两种做法,一种是变成他们的lcm这样的话,修改后答案应该是减去改过的个数然后在加一 另一种就是数字修改成序列中的倍数,比如如果序列中有4和8,修改一次把4变成8,这样剩下的数字就只有一个;比较这两个

1.面向对象 面向对象是一种思想,是基于面向过程而言的,就是说面向对象是将功能等通过对象来实现,将功能封装进对象之中,让对象去实现具体的细节,我们由以前过程的执行者,变成了指挥者。 举例来说:就是:比如说你要去饭店吃饭,你只需要饭店,找到饭店的服务员,跟她说你要吃什么,然后就会给你

In a row of dominoes, A[i] and B[i] represent the top and bottom halves of the i-th domino. (A domino is a tile with two numbers from 1 to 6 - one on each half of the tile.) We may rotate the i-th domino, so that A[i] and B[i] swap values. Return
哈希码: hashCode的作用是用来获取哈希码,也可以称作散列码。实际返回值为一个int型数据。用于确定对象在哈希表中的位置。 Object中有hashcode方法,也就意味着所有的类都有hashCode方法。 因为hashCode()并不是完全可靠,有时候不同的对象他们生成的hashcode也会一样(生成hash值得
