Problem Explanation

Explanation:

To calculate the year-on-year growth rate for a given array of numbers representing yearly revenue, we can use the formula: (current year revenue - previous year revenue) / previous year revenue * 100. We will iterate through the array once and calculate the growth rate for each pair of consecutive years. :

Solution Code

public double[] calculateYearOnYearGrowthRate(int[] revenue) {
    double[] growthRate = new double[revenue.length - 1];
    for (int i = 1; i < revenue.length; i++) {
        growthRate[i - 1] = ((double) revenue[i] - revenue[i - 1]) / revenue[i - 1] * 100;
    }
    return growthRate;
}
