The first line contains an integer, (the initial number of elements in ). The second line contains space-separated integers describing . The third line contains an integer, (the number of queries). The subsequent lines describe the queries, and each query is described over two lines: . If the first line of a query contains the String Insert, then the second line contains two space separated ...
Java Datatypes. Java has 8 primitive data types; char, boolean, byte, short, int, long, float, and double. For this exercise, we'll work with the primitives used to hold integer values (byte, short, int, and long): A byte is an 8-bit signed integer. A short is a 16-bit signed integer. An int is a 32-bit signed integer.
