Question

For the questions below, assume that int[ ] a = {6, 2, 4, 6, 2, 1, 6, 2, 5} and consider the two recursive methods below foo and bar.
public int foo(int[ ] a, int b, int j)
{
if (j < a.length)
if (a[j] != b) return foo (a, b, j+1);
else return foo (a, b, j+1) + 1;
else return 0;
}
public int bar(int[ ] a, int j)
{
if (j < a.length)
return a[I] + bar(a, j+1);
else return 0;
}
-What is the result of calling bar(a, 0);?
A) 0
B) 5
C) 6
D) 12
E) 34
