Write a program in C$++$ first reads integer certificateCount from input, representing the number of pairs of inputs to be read. Each pair has a

string and an integer, representing the certificate's holder and level, respectively. One Certificate object is created for each pair and

added to vector certificateList. Output "Average certificate level: $",$ followed by the average level of all the Certificate objects as an

integer. End with a newline.

Ex: If the input is:

$3$

Bob $5$ Eve $12$ Pat $13$

then the output is:

Average certificate level: $10$

Note: The ArrayList has at least one element.
