At first, the computer operating system was 32 bits, and the time was expressed as 32 bits.System. Out. println (integer. max_value );2147483647Integer is represented by 32 bits in Java, so the maximum value expressed by 32 bits is 2147483647. In addition, the total number of seconds for the second day of the year is 365,2147483647/31536000 = 68.1That is to say, the maximum time that 32 bits can represent is 68 years. In fact, by, January

Assume is s a string of lower case characters.Write A program This prints the longest substring of in s which the letters occur in alphabetical order. For example, if s = ‘azcbobobegghakl‘ , then your program should printLongest substring in alphabetical order Is:begghIn the case of ties, print the first substring. For example, if s = ‘abcbcd‘ , then your program should printLongest substring in alphabetical order IS:ABC# Paste Your code into this boxCount = 1result = S[0]While S:Newcount = 1New

My computer history (programming) (Part 1)I can't remember the first few times that I couldn't sleep late at night and wanted to get up and write something. Recently I read many history of my computers, and wrote a lot of good stuff. It also aroused many memories of my childhood, those memories are full of passion. So I want to recall my computer.
