Exam 13: Recursion

Consider the method below, which prints the digits of an arbitrary positive integer in reverse order, one digit per line.The method should print the last digit first.Then, it should recursively print the integer obtained by removing the last digit.Select the statements that should be used to complete the method.

Consider the method powerOfTwo shown below: What is the best interpretation of line #1?

Consider the getArea method from the book shown below. What will happen when this code is executed?

Which of the following executions represent mutual recursion? i.method E calls method T, which calls method F II.method E calls method T, which calls method F, which calls method E III.method F calls method F

Assume that recursive method search returns true if argument value is one of the elements in the section of the array limited by the firstIndex and lastIndex arguments.What statement can be used in main to determine if the value 7 is one of the elements in array values?

A termination condition in a loop is analogous to _____________ in a recursive method.

Complete the code for the calcPower recursive method shown below, which is intended to raise the base number passed into the method to the exponent power passed into the method:

If recursion does not have a special terminating case, what error will occur?

Recursion does NOT take place if any of the following happen: i.method A calls method B, which calls method C, which calls method B II.method A calls method B, which calls method A III.method A calls method B, B returns, and A calls B again
