1. Write a function called sum_arrays that takes two lists of the same length and returns a list where each element is the sum of the elements at that index in the original list. The function should return the empty list if the parameters are not the same size Sample Run 1:
a = [1, 2, 3, 4, 5]
b = [10, 20, 30, 40, 50]
print(sum_arrays(a, b))

Should output:
[11, 22, 33, 44, 55]

Sample Run 2:
a = [1, 2, 3, 4, 5]
b = [10, 20, 30, 40, 50, 60]
print(sum_arrays(a, b))

Should output:
[]

2. Write a function called replace_elem that takes an array and two values and uses the simple search algorithm to replace all instances of the first value with the second value
Sample Run 1:
a = [7, 4, 10, 3, 7, 2, 4, 5]
print(replace_elem(a, 4, 6))

Should output:
[7, 6, 10, 3, 7, 2, 6, 5]

Sample Run 2:
a = [7, 3, 10, 3, 7, 2, 9, 5]
print(replace_elem(a, 4, 6))

Should output:
[7, 3, 10, 3, 7, 2, 9, 5]
