Searching for the number of substrings in a given text that start with the letter A and end with the letter B. For example, in the DABAAKBSA text, there are 4 substrings that begin with the letter A and end with the letter B. a) Design a brute-force algorithm that performs the desired operation above and implement it in c language. Let the searched text be entered by the user.

b) Calculate the time complexity of the algorithm you designed.

c) Design an algorithm that is more efficient than the brute-force algorithm and implement it in c language. Let the searched text be entered by the user.

d) Calculate the time complexity of the algorithm you designed and compare it with the brute-force algorithm.

Consider the following code snippet: #ifndef cashregister_h#define cashregister_hconst double max_balance = 6000000.0; class cashregister{public: cashregister(); cashregister(double new_balance); void set_balance(double new_balance); double get_balance() const; private: double balance[12]; }; double get_monthly_balance(cashregister bk, int month); #endifwhich of the following is correct? a)the header file is correct as given.b)the definition of max_balance should be removed since header files should not contain constants.c)the definition of cashregister should be removed since header files should not contain class definitions.d)the body of the get_monthly_balance function should be added to the header file.

Rafael needs to add a title row to a table that he has inserted in word. what should he do? use the alignment options. use the merge and center option for all the cells in the top row. use the merge and center option on the first two cells in the top row. none of the above
