feat: Implement element deletion from array by index with left shift

🧠 Logic:
- Initialize an array `A` with 6 elements and size tracker `n = 6`.
- To delete an element at a given `index`, shift all subsequent elements one position to the left.
- Decrease the array size (`n--`) to exclude the last redundant value.
- Print the array before and after deletion to visualize the change.
