    描述

    Boudreaux and Thibodeaux are on the road again . . .

    "Boudreaux, we have to get this shipment of mudbugs to Baton Rouge by tonight!"

    "Don't worry, Thibodeaux, I already checked ahead. There are three underpasses and our 18-wheeler will fit through all of them, so just keep that motor running!"

    "We're not going to make it, I say!"

    So, which is it: will there be a very messy accident on Interstate 10, or is Thibodeaux just letting the sound of his own wheels drive him crazy?

    输入

    Input to this problem will consist of a single data set. The data set will be formatted according to the following description.

    The data set will consist of a single line containing 3 numbers, separated by single spaces. Each number represents the height of a single underpass in inches. Each number will be between 0 and 300 inclusive.

    输出

    There will be exactly one line of output. This line will be:

    NO CRASH

    if the height of the 18-wheeler is less than the height of each of the underpasses, or: CRASH X

    otherwise, where X is the height of the first underpass in the data set that the 18-wheeler is unable to go under (which means its height is less than or equal to the height of the 18-wheeler). The height of the 18-wheeler is 168 inches.

    样例输入

    180 160 170
    

    样例输出

    CRASH 160
    

    中文题面:

    布德罗和蒂博多再次上路了……

    “布德罗,我们必须在今晚之前把这一批小龙虾送到巴吞鲁日!”

    “别担心,蒂博多,我已经提前查看过了。有三个地下通道,我们的十八轮大卡车都能通过,所以只要让引擎继续运转就行!”

    “我们到不了的,我说!”

    那么,问题来了:在第10州际公路上会发生一场非常混乱的事故,还是蒂博多只是被他自己车轮的声音逼疯了? 输入 这个问题的输入将由一个单一的数据集合成。数据集的格式将按照以下描述进行格式化。

    数据集将由一行组成,包含33个数字,以单个空格分隔。每个数字代表一个地下通道的高度(以英寸为单位)。每个数字将在03000到300之间,包括03000和300。 输出 输出将只有一行。 如果十八轮大卡车的高度低于每个地下通道的高度, 则输出为:

    NO CRASH

    否则,输出为:

    CRASH X

    其中X是数据集里第一个十八轮大卡车无法通过的地下通道的高度(这意味着它的高度小于或等于十八轮大卡车的高度)。

    十八轮大卡车的高度是168168英寸。

    180 160 170
    

    样例输出

    CRASH 160
    

    算法标签

    if语句

    解题思路

    读取输入,检查第一个地下通道的高度是否小于或等于 limitlimit,如果是,则输出 "CRASHCRASH" 和该高度。 如果第一个地下通道的高度大于 limitlimit,则继续检查第二个地下通道的高度。以此类推,如果所有地下通道的高度都大于 limitlimit,则输出 "NOCRASHNO CRASH"。

    实现步骤

    1.声明三个整数变量 h1,h2,h3h1, h2, h3存储地下通道的高度。 2.定义一个常量 limit=168limit = 168 表示十八轮大卡车的高度。 3.使用 ifif 语句判断每个地下通道的高度是否小于或等于 limitlimit

    C++实现

    #include <iostream>
    #include <stdio.h>
    using namespace std;
    int main(){
        int h1,h2,h3;
        cin>>h1>>h2>>h3;
        int limit=168; 
        if(limit>=h1){
            printf("CRASH %d",h1);
            return 0;
        }else if(limit>=h2) {
            printf("CRASH %d",h2);
            return 0;
        }else if(limit>=h3){
            printf("CRASH %d",h3);
            return 0;
        }else{
            printf("NO CRASH");
        }
        return 0;
    }
