1. Make a large tree trunk. 2. Use real leaves to create the rest of the tree. 3. If you can't use real leaves, have students trace their hands on fall colored construction paper. Arrange on the tree trunk to form a tree.
Xcode is an integrated development environment for macOS containing a suite of software development tools developed by Apple for developing software for macOS, iOS, watchOS and tvOS.
The XOR gate (sometimes EOR gate, or EXOR gate and pronounced as Exclusive OR gate) is a digital logic gate that gives a true (1/HIGH) output when the number of true inputs is odd. An XOR gate implements an exclusive or; that is, a true output results if one, and only one, of the inputs to the gate is true. If both inputs are false (0/LOW) or both are true, a false output results. XOR represents the inequality function, i.e., the output is true if the inputs are not alike otherwise the output is false. A way to remember XOR is one or the other but not both. XOR can also be viewed as addition modulo 2. As a result, XOR gates are used to implement binary addition in computers.
