Her factory has introduced M new machines in order to process the coming N tasks. For the i-th task, the factory has to start processing it at or after day Si, process it for Pi days, and finish the task before or at day Ei. A machine can only work on one task at a time, ...
How can we reuse a previously computed palindrome to compute a larger palindrome? 提示2 If “aba” is a palindrome, is “xabax” a palindrome? Similarly is “xabay” a palindrome? 提示3 Complexity based hint: If we use brute-force and check whether for every start and end position a...
Given two strings s and t, determine if they are isomorphic. Two strings are isomorphic if the characters in s can be replaced to get t. All occurrences of a character must be replaced with another character while preserving the order of characters. No two characters may map to the same c...
要么借助于enumerate方法: presidents = ["Washington", "Adams", "Jefferson", "Madison", "Monroe", "Adams", "Jackson"] for num, name in enumerate(presidents, start=1): print("President {}: {}".format(num, name)) 详细的解释可以参考这个帖子: treyhunner.com/2016/04/ 如果在Java中(C++中...
Given a string containing only digits '0'-'9', write a function to determine if it’s an additive number. Follow up: How would you handle overflow for very large input integers? 【解答】在最开始的两个数定了以后,后面就一路计算和检查下去,看是不是 additive number 就好了。因此在最开始使...
The first3 bits are all one's and the 4th bit is 0 means it is a 3-bytes character.The next byteisa continuation byte which starts with 10andthat's correct.But the second continuation byte doesnotstart with 10, so itisinvalid.
