Declare and initialize a reference variable for an ArrayList named heightList that stores items of type Integer. Read ir

startHeight and numHeights from input. Then, insert the following integers into heightList:

startHeight, startHeight $***2,$ startHeight $***2***2$dots, and so on until numHeights integers have been inserted.

Ex: If the input is $1,3,$ then the output is:

$124$
