Check if list is sorted Program Code

def is_sorted(arr):
    if len(arr) <= 1:
        return True
    if arr[0] > arr[1]:
        return False
    return is_sorted(arr[1:])

arr1 = [10, 20, 30, 40, 50]
arr2 = [10, 30, 20, 40, 50]
print(f"arr1 sorted? {is_sorted(arr1)}")
print(f"arr2 sorted? {is_sorted(arr2)}")
