Write a program to create a binary search tree where each node has a counter to store how many times its value occurs in the tree, and then prints the pre-order, in-order and post-order transversals of the modified tree. The values that occur more than once are followed with their quantity noted in parenthesis. Input from the keyboard a single line of integer numbers separated by spaces. Assume proper input and no more than 30 values. Output to the screen the pre order, in order, and post order traversals on separate lines. Quantities larger than one are denoted with parenthesis. Each row must be properly labeled and use a minimum of one space between each number. Use a tree data structure. Refer to the sample output below. Sample Run:
Enter up to 30 integer values: 7 1 5 7 4 4 1 8 9 7 1 4 2 2 3 5 6 7 12 14 11 12
Pre Order: 7(4) 1(3) 5(2) 4(3) 2(2) 3 6 8 9 12(2) 11 14
In Order: 1(3) 2(2) 3 4(3) 5(2) 6 7(4) 8 9 11 12(2) 14
Post Order: 3 2(2) 4(3) 6 5(2) 1(3) 11 14 12(2) 9 8 7(4)

Local area networks use many of the same network technologies and the internet, only on a smaller scale. devices that access lans are equipped with a network interface that contains circuitry for wireless or wired connections. devices also have a physical address, in addition to the ip addresses acquired from a dhcp server. the most popular wired technology is . the most popular wireless technology is , which can be configured as a(n) or star topology. setting up a lan and configuring its router is fairly easy. the first step is to change the standard to one that is secure. next, create a(n) that uniquely identifies the network by name. it is also important to activate wireless to prevent wireless signals from being intercepted during transmission. a limited-access network can be created for visitors to use. by activating , the router will be able to assign ip addresses to each device that joins the network. to connect to a secure lan that is protected by encryption, an encryption , or password, is required. lans can be used to access data collected by iot devices and the networks that tie these devices together. technologies such as rfid, nfc, bluetooth smart, zigbee, and z-wave offer -power links, essential for battery-powered devices that can’t expend excess amounts of energy transmitting data.
