用java进行的尝试

解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main{

public static void main(String[] args){

Scanner myScanner = new Scanner(System.in);

int n=myScanner.nextInt();

int count=0;//保持正常血压的小时数

int j=0;//血压不正常前，保持正常血压的最长时间数

for(int i=1;i<=n;i++){

int shou=myScanner.nextInt();

int shu=myScanner.nextInt();

if(shou>=90&&shou<=140&&shu>=60&&shu<=90)

count++;

else{

if(count>j)

j=count;

    count=0;

}

}

j=count>j?count:j;

System.out.println(j);

}  

}
