[Recursion: CLO: 5] [7.5 Pts]

Important Note 1: Your program should compile and run correctly!

To convert a number from the base-2 number (binary format) to the base-10 (decimal) format, the following process is done.

Number (base 2) = 1110011

Number (base 10) = 1x2⁶ + 1x2⁵ + 1x2⁴ + 0x2³ + 0x2² + 1x2¹ + 1x2⁰

= 64 + 32 + 16 + 0 + 0 + 2 + 1 = 115

The above binary-to-decimal algorithm can be implemented in two different ways:

• Iterative
• Recursive

1. Complete the iter_bin2dec() method in the NumberConvert class to perform the iterative version of the binary to decimal format number conversion algorithm. Consider the following signature: [3 Pts]

public static int iter_bin2dec(String bin)

2. Complete the recur_bin2dec() method in the NumberConvert class to perform the recursive version of the binary to decimal format number conversion algorithm. Consider the following signature: [3 Pts]

public static int recur_bin2dec(String bin, int start)

3. Complete the test_bin2dec () method in the NumberConvert class to convert the binary number given as a String 1110011 [1.5 Pts]

public static void test_bin2dec()
