# A method named `binary_to_decimal` that receives as input an array of size 8.
# The array is randomly filled with 0’s and 1’s.
# The most significant bit is at index 0.
# The least significant bit is at index 7.
# Calculate and return the decimal value for this binary number using
# the algorithm you devised in class.

This works, but you've hardcoded for specific powers of 2. Could you find a way to make this more flexible?

binary_array.each_with_index do |number, index|
if number == 1
sum += decimal_array[index]
end
end
return sum
end
