# Take array
n = int(input("Enter array size: "))
arr = []
for i in range(n):
    arr.append(int(input(f"Element {i+1}: ")))

# Find index of max
max_index = 0
max_value = arr[0]

for i in range(1, len(arr)):
    if arr[i] > max_value:
        max_value = arr[i]
        max_index = i

print(f"Index of maximum: {max_index}")

Output

Enter array size: 5
Element 1: 10
Element 2: 25
Element 3: 5
Element 4: 30
Element 5: 15
Index of maximum: 3

Track both value and index.
