Answer the following statements true (T) or false (F)
1. When a program is executed, array element indices are checked for validity—all indices must be greater than or equal to 0 and less than or equal to the length of the array.
2. ComboBox property ItemSource specifies the source of the items displayed in the ComboBox.
3. String method Replace receives two arguments—the substring that should be replaced throughout the original String and the replacement substring.
4. To pass an array argument to a method, specify the name of the array followed by empty parentheses.
5. An individual element of an integer array is passed to a method by value.
1. False: When a program is executed, array element indices are checked for validity—all indices must be greater than or equal to 0 and less than the length of the array.
2. False. ComboBox property DataSource specifies the source of the items displayed in the ComboBox.
3. True.
4. False. To pass an array argument to a method, specify the name of the array without using parentheses.
5. True.
False. Arrays are passed to methods by reference; therefore, changes made within the method modify the original array itself.

Routing algorithms choose a next hop according to an estimate of distance in some addressing space. Pastry and Tapestry both use circular linear address spaces in which a function based on the approximate numerical difference between GUIDs determines their separation. Kademlia uses the XOR of the GUIDs. How does this help in the maintenance of routing tables? Does the XOR operation provide appropriate properties for a distance metric?
