好吧,我很难找到答案,因为我不知道如何用英语来表达这一点!所以,

我试图做最长的Nap 问题: https://uva.onlinejudge.org/external/101/10191.pdf

我的代码正在运行,但我一直收到来自法官的错误答案,我认为问题是当我连续输入两个测试用例时。

我输入:

1 
12:00 13:00 schedule A

这样:

Day #1: the longest nap starts at 13:00 and will last for 5 hours and 0 minutes.

但如果我输入:

1
2

数字2被忽略作为一个新的测试案例,我认为这就是为什么我从法官那里得到错误答案

所以我想要输入的第二个数字,我的代码中第二个scanf捕获的数字是新的测试用例。我尝试在我的switch case中添加一个案例1:我强制testcase是initH,因为我输入的新测试用例被这个变量捕获但没有成功

    while(scanf("%d", &testcase) == 1) {

    int result = 0, start;

    if(testcase > MAXVALUE)  continue;
     //here I ignore testcase > 100
    if(testcase == 0) {ret = SCANF; start = STARTIME; result = WORK;}
     //if there's no testcase my longest nap will be the 8 hours! SCANF = 5

    for(i = 0; i < testcase; i++) {
        ret = scanf("%d:%d %d:%d %255[a-zA-Z ]", &initH, &initM, &fintH, &fintM, appoint);
         //variables: H(hour), M(minute), appointment

        switch (ret){
        case 5:
            schedule[i].start = initH*HOUR + initM; //struct here
            schedule[i].endin = fintH*HOUR + fintM; //to keep this data
            break;
        default:
            i = testcase;
            break;
        }

        if((initH < INIT) || (fintM + fintH*HOUR) > ENDTIME) {error++; break;}
         //10:00 < time < 18:00 
        if((initH*HOUR + initM) > (fintH*HOUR + fintM)) {error++; break;}
         //initial hour in a schedule < end time in a schedule

        while(getchar() != '\n');
    }

    if(error != 0) {error = 0; continue;} //if error then ignore everything!

1 个答案:

答案 0 :(得分:0)

好吧,昨天我一直坚持这一点,当我决定寻求帮助时,我找到了解决方案!实际上非常简单!

if(ret == 5){ //only if I have 5 arguments in my scanf!
    if((initH < INIT) || (fintM + fintH*HOUR) > ENDTIME) {error++; break;}
    //10:00 < time < 18:00 
    if((initH*HOUR + initM) > (fintH*HOUR + fintM)) {error++; break;}
    //initial hour in a schedule < end time in a schedule
}
