Throttle Simulation

MediumApp Logic (real-world)

The problem

Given event timestamps and an interval, output the times at which a throttled callback fires (leading edge — at most one call per interval). Used to limit scroll / resize handlers.

Sample input

events = [0,50,100,250,300,500], interval = 200

Sample output

0 250 500

fun main() {
    val events = intArrayOf(0, 50, 100, 250, 300, 500)
    val interval = 200
    val fires = mutableListOf<Int>()
    var lastFire: Int? = null
    for (t in events) {
        if (lastFire == null || t - lastFire!! >= interval) {
            fires.add(t)
            lastFire = t
        }
    }
    println(fires.joinToString(" "))
}
