The solution has the complexity below and needs a comment for the logic

• Complexity:
  • () time
  • (1) space

The output should look like this,

def hobby(arr): Find the first and second largest element in the array You may assume the array has at least two unique elements Parameters arr : a list of integers Returns [the first largest element, the second largest element] : a list of two integers # Print arr_1 arr_2 arr_3 arr_4 II II II 11 [2, 3] [3, 2, 3] [2, 3, 5, -4] [2, 3, 5, -4, 9, 10, 20, 11] print(hobby(arr_1)) print(hobby(arr_2)) print(hobby(arr_3)) print(hobby(arr_4)) [3, 2] [3, 3] [5, 3] [20, 11]
