Question

Question 11 (3 points) What does the following recursive method determine? public boolean question 16(int[]a, int[] b. intj) { if (j == 2.length) return false; else if ( == b.length) return true; else return question 16(2, b.j+1): 3 returns true if b contains less elements than a, false otherwise returns true if b contains more elements than a, false otherwise returns true if a and bare equal in size, false otherwise returns true if a's element value is larger than b. false otherwise

Answer 1

A. returns true if b contains less elements than a, false otherwise

The question16 returns true if the length of b is less than length of a. Otherwise false is returned.

Suppose the length of a = 5, length of b = 3 and j = 1.

The initial function call would be:

question16(5,3,1) // returns question16(5,3,2)

question16(5,3,2) //  returns question16(5,3,3)

question16(5,3,3)   // returns true

One more scenario can be checked by connsidering length of a = 3, length of b = 5 and j = 1.

question16(3,5,1) // returns question16(3,5,2)

question16(3,5,2) //  returns question16(3,5,3)

question16(3,5,3) // returns false
