Write a function NumberOfBits(n) , that takes as input a number, n, where n is bigger or equal to 1, and returns the minimum number of bits that n needs to be represented in binary. The number of bits needed for representation in binary for any integer is equal to 1 + the number of times you can divide that number by 2. for example , the number 10 can be divided by 2 three times : 10/2 = 5 , 5/2= 2.5 , 2.5/2 =1.25. thus, 10 need (1 + 3=) 4 digits to be represented in binary as 1010.(provide complete and meaningful docstrings)

>>>NumberOfBits(4) 3

>>>NumberOfBits(15) 4
