For each of the following grammars state whether it is ambiguous or unambiguous. If it is ambiguous, give an equivalent unambiguous grammar and state all the precedence and the associativity enforced by the unambiguous grammar. If it is unambiguous, state all the precedence and the associativity enforced by the unambiguous grammar. a. E :: = E + F | F
F ::= F* F | Id |(E)

b. E :: = F â© E | F U E | F
F :: = F^ G| F v G |G
G:: = Id | (E)

Write a program that inserts the digits of an integer into an array in originalorderfollowed by reverse order. first, promptthe user to enter a positive integer(> 0). determine the number of digits of the integer. create a dynamically allocated integer arrayof a size twice the number of digits. now insert the digits in original order which will occupy half of the array. then, insert the digits in reverse order. finally, output thedigits in thearray. use at least two functions to organize your program.
