1018. Find the smallest integer in the array

Given an array of integers your solution should find the smallest integer.

For example:

• Given [34, 15, 88, 2] your solution will return 2
• Given [34, -345, -1, 100] your solution will return -345

You can assume, for the purpose of this kata, that the supplied array will not be empty.

Solution:

# 1
def find_smallest_int(arr):
    return sorted(arr, reverse=True).pop()

# 2
def find_smallest_int(arr):
    return min(arr)

# 3
find_smallest_int = min
