Composing multiple flows

In Kotlin, it’s common to need to combine or transform multiple flows into a single stream of data. Here are a few examples of how you can compose multiple flows:

1. zip operator: This operator combines two flows into a single flow of pairs. It emits the first item from each flow, then the second item from each flow, and so on. For example:

val numbers = flowOf(1, 2, 3)
val letters = flowOf("a", "b", "c")

numbers.zip(letters) { number, letter ->
    "$number$letter"
}.collect { combined ->
    println(combined)
}
// Output: 1a 2b 3c

2. combine operator: This operator combines two or more flows into a single flow that emits a new value each time any of the source flows emit a value. For example:
