Array & Pointer Visualizer

Interview-style, array-based algorithms with explicit pointer movement.

1) Array Generator

Input array Random array

Array values (comma separated)

Array size

Maximum element value

Allow duplicates

Array values are random integers from 0 to max (inclusive).

How many pointers?

Pointer names (comma separated)

Pointers start at index 0 unless you override below. Negative and out-of-bounds values are allowed.

Allowed step values (comma separated)

Operations

+= -= *= /=

Swap (choose pointers or enter indices)

Update array value

Use pointer Use index

Pointer moves can go out of bounds; those cells are shown in red stripes.

Search values (comma separated)

Tip: click any array cell to add that value to the search.
