length of 20. Now the machine has 8 GB of memory. How can this problem be solved. Iii. System Design Questions Forward maximum matching algorithm (FMM) for Chinese Word Segmentation in natural language processing ). Note: The example explains the basic idea of FMM. (1) design the data structure struct dictnote of the dictionary. (2) Use C/C ++ to implement FMM. The optional interface is Int FMM (vector Here, iletters is the sentence to be segmented, such as {"small", "Ming", "today", "day", "b

Questions that students need to write on the computer when they go to Shanghai Tongji Urban Planning and Design Institute Write a function bool fun (char * t, char * s)T is the template string, where * represents 1 to n arbitrary characters, and s is the matching string. True is returned for matching, whereas false is returned.For example:AB * and ABC matchAB * And ACD do not matchA * BC and adebc matchA * BC and adebce do not matchA * BC and a ** BC matchB * de * C and bfddsdessscc match Recu

simply use an index instead of creating an iterator object. Linklist also creates objects for each inserted element, all of which you have to understand that it also brings additional overhead.Finally, in the book Practical Java, Peter Haggar suggests using a simple array instead of a vector or ArrayList. This is especially true for programs with high efficiency requirements. Because the use of arrays (array) avoids synchronization, additional method calls, and unnecessary reallocation of space

A point of view of their own, there is a wrong place please advise1, A,b,c is a global variable, two threads execute the following code in parallel, then the final result of a may beFour statement permutations (the statement order of each program cannot be reversed)The result is 4,13,15,26Note: There is no writeback problem, because a,b,c are global variables, two threads share these variables, and there are no self-operating operators in the program, so there is no writeback problem2.Answer aNo
