Problem Description You are the CEO of Nasty Hacks Inc., a company that creates small pieces of malicious software which teenagers may use to fool their friends. The company has just finished their first product and it is time to sell it. You want to make as much money as possible and consider advertising in order to increase sales. You get an analyst to predict the expected revenue, both with and without advertising. You now want to make a decision as to whether you should advertise or not, given the expected revenues.
Input The input consists of n cases, and the first line consists of one positive integer giving n. The next n lines each contain 3 integers, r, e and c. The first, r, is the expected revenue if you do not advertise, the second, e, is the expected revenue if you do advertise, and the third, c, is the cost of advertising. You can assume that the input will follow these restrictions: -106 ≤ r, e ≤ 106 and 0 ≤ c ≤ 106.
Output Output one line for each test case: “advertise”, “do not advertise” or “does not matter”, presenting whether it is most profitable to advertise or not, or whether it does not make any difference.
Sample Input 3 0 100 70 100 130 30 -100 -70 40
Sample Output advertise does not matter do not advertise
嗯。。水题。。
题意就是输入的： 第一个数a是：做研发能赚多少钱，负数代表亏多少钱。 第二个数b是：做广告能赚多少钱。 第三个数c是：做广告的成本。 也就是比较a和(b c)谁大谁小，还是相等。 如果a大：输出：do not advertise 如果a小：输出：advertise 如果一样大：输出：does not matter
代码语言：javascript复制import java.util.Scanner;
public class Main{
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int t =sc.nextInt();
while(t-->0){
int a =sc.nextInt();
int b =sc.nextInt();
int c =sc.nextInt();
if(a==(b-c)){
System.out.println("does not matter");
}else if(a>(b-c)){
System.out.println("do not advertise");
}else{
System.out.println("advertise");
}
}
}
}
