没有签什么NDA,网上也没看到多少A9面经，发一记分享给大家～1. Given an array of integers and a number N, write a function to rotate the array to the right by N positions
For example
Given an array = [A,B,C,D,E,F,G,H] with N=3, the result will be [F,G,H,A,B,C,D,E]
follow up: protect your function against malicious inputs
2.Given 3 array of Strings.
Array one = {Red, Green, Blue}
Array two = {Large, Medium, Small}
Array three={giant, monster}
Print out combinations of all three array.
public void combination(String[][] arrays) {}

3.
Given an array of 1,000,000 integers where each integer is between 0 and 2^20 - 1
Find one integer that is between 0 and 2^20 -1 that is not in the array.
Hint: 2^20 = 1,048,576 > 1,000,000. That means there are at least 48,576 integers that are not in the array. 涓€浜�-涓夊垎-鍦帮紝鐙鍙戝竷
