题目信息

题目描述和附件分别是一串数字和新加坡日历，数字中间有短线-连接，刚好分成了12个字段。猜想对应了12个月

解题过程

使用python脚本将代码按照‘-’分割：

s = '01081522291516170310172431-050607132027262728-0102030209162330-02091623020310090910172423-02010814222930-0605041118252627-0203040310172431-0102030108152229151617-04050604111825181920-0108152229303124171003-261912052028211407-04051213192625';
left = 0;
right = 0;
anslist = [];
for i in range(0,len(s)):
    if s[i] == '-':
        right = i;
        curlist = s[left:right];
        print("curlist------>",curlist)
        anslist.append(curlist)
        left = right+1;
anslist.append(s[left:len(s)])
print(len(anslist))
print("anslist->",anslist)

可以得到结果为：
curlist------> 01081522291516170310172431
curlist------> 050607132027262728
curlist------> 0102030209162330
curlist------> 02091623020310090910172423
curlist------> 02010814222930
curlist------> 0605041118252627
curlist------> 0203040310172431
curlist------> 0102030108152229151617
curlist------> 04050604111825181920
curlist------> 0108152229303124171003
curlist------> 261912052028211407
curlist------>04051213192625

把这些数字两两一组分隔开，在日历上圈出来：

flag为：HITB{CTFFUN}
