Have devised a new encryption technique which encodes a message by inserting between its characters randomly Strings in a clever way. Because of pending patent issues we won't discuss in detail how the strings are generated and inserted into the Origina L message. To validate your method, however, it's necessary to write a program that's checks if the message was

Program Introduction: Sometimes we want to know which tables are in a database and what fields are in the table. I wrote a small program to implement this function.
Ideas:1: connect to the database (nonsense)
2: obtain all the tables in the database and cache them.
3: for each table, execute the SQL command select * from XXX and output their header (if you can think of a better method, I hope to tell you ).
Code:

necessary to write a program that checks if the message was really encoded in the F Inal string.Given-strings s and T, you had to decide whether s are a subsequence of T, i.e. if you can remove characters from T su CH, the concatenation of the remaining characters is S.InputThe input contains several testcases. Each are specified by and strings s, T of alphanumeric ASCII characters separated by whitespace. The length of S and T would no more than 100000.OutputFor each test, the output "Yes", if
Question: 10340-all in allReturns the string S and T and asks if S is a substring of T. If the characters removed by s can be the same as T, T is a substring of S.Solution: Match characters. Each character of T matches the character in S. Note that the size of the character array must be greater.Code:# Include
