How to implement three stacks using a single array

Witryna19 wrz 2024 · The second stack begins at index 1 and uses indices 1, 4, 7, 10 and so on. Indexing into the array for a top operation uses the formula i + n * (sizes [i] - 1), while pushing a new top is i + n * sizes [i] where i is the stack ID number and n is the number of stacks specified in the constructor. Witryna10 maj 2024 · We can also easily use a single array to implement two stacks.
