Create a Flux of 1, 2, 3, 4, 5 and use scan() to compute a running total. Print each intermediate sum.

scan() is like reduce() but emits each intermediate accumulation.

Create a Flux of 1, 2, 3, 4, 5 and use scan() to compute a running total. Print each intermediate sum.

scan() is like reduce() but emits each intermediate accumulation.

Why this works

scan() works like reduce() but emits each intermediate accumulation as it processes elements. This is useful for running totals, state machines, and progressive computations. skip(1) omits the initial seed value.
