You are given an array of integers a$.$ A new array b is generated by rearranging the elements of a in the following way:

b$[0]$ is equal to a$[0]$;

b$[1]$ is equal to the last element of a;

b$[2]$ is equal to a$[1]$;

b$[3]$ is equal to the second$-$last element of a;

b$[4]$ is equal to a$[2]$;

b$[5]$ is equal to the third$-$last element of a;

and so on$.$

Your task is to determine whether the new array b is sorted in strictly ascending order or not.
