please provide the answer in C++ with simple step by step coding 9. (Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs increment the counter variable that's keeping count of the 1s that occur; and so on. finally display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.

Please use C++ Extend and implement the Dynamic Programming Algorithm in the last example of the relevant slides so that it prints a parenthesized expression yielding the goal or “No parenthesization possible.” if no such parenthesization exists. Input format (no need to check its validity): The first line contains a positive integer (say n). The symbols: The second line contains at least n characters (if it contains more, only the first n are relevant). These characters are the symbols of the alphabet. The last symbol is the “goal”. The operation: The following n lines contain at least n characters each (if a line contains more characters, only the first n are relevant). This is an nxn matrix containing the results of the operations. Expression: The last line of the input contains a sequence of characters, consisting of the valid symbols for which you have to seek for a parenthesization. A sample input: 3 abc aac baa caa caaccb and corresponding possible outputs (not exhaustive):…
This is a predicate logic question Let P(x) mean "x is a program"; F(x) mean "x is a function"; and I(x,y) mean "x invokes y". Choose all options whose predicate logic formula and statement correspond. Select one or more: 1) "Only programs invoke functions" and ∀x∀y(F(x)∧I(y,x)→P(y)) 2) "Some programs do not invoke some functions" and ∃x∃y(P(x)∧F(y)→¬I(x,y)) 3) "Some functions do not get invoked by some programs" and ∀x(P(x)→∀y(F(y)→¬I(x,y))) 4) "Every program invokes every function" and ∀x∀y(P(x)∧F(y)∧I(x,y))
