9. Read a list of n elements. Pass this list to a function which reverses this list in-place without creating a new list.
Ans. def reverseInPlace(inputList):
start, end = 0, len(inputList) - 1

while start < end:
inputList[start], inputList[end] = inputList[end], inputList[start]
start += 1
end -= 1

n = int(input("Enter the number of elements: "))

myList = []
for i in range(n):
element = int(input(f"Enter element {i + 1}: "))
myList.append(element)

print("\nOriginal List:", myList)

reverseInPlace(myList)

print("Reversed List in Place:", myList)
