Discussion on: Daily Challenge #120 - Growth of a Population

[kesprit]

Swift solution :

func nbYears(populationOrigin: Int, percent: Float, aug: Int, populationTarget: Int) -> Int {
    var numberOfYears = 0
    guard populationOrigin > 0, populationTarget > 0 else { return numberOfYears }
    var increasePopulation = Double(populationOrigin)
    while increasePopulation < Double(populationTarget) {
        increasePopulation += (increasePopulation * Double(percent / 100)) + Double(aug)
        numberOfYears += 1
    }
    return numberOfYears
}
