Question: 
Write a function to find the fixed point in the given array.


Model's Code:
def find_fixed_point(arr, n):
    for i in range(n):
        if arr[i] == i:
            return i
    return -1



Sample Correct Code:
def find_fixed_point(arr, n): 
	for i in range(n): 
		if arr[i] is i: 
			return i 
	return -1


Asserts:
assert find_fixed_point([-10, -1, 0, 3, 10, 11, 30, 50, 100],9) == 3
assert find_fixed_point([1, 2, 3, 4, 5, 6, 7, 8],8) == -1
assert find_fixed_point([0, 2, 5, 8, 17],5) == 0
