+<h2><a href="https://leetcode.com/problems/minimum-time-to-complete-all-deliveries">4048. Minimum Time to Complete All Deliveries</a></h2><h3>Medium</h3><hr><p>You are given two integer arrays of size 2: <code>d = [d<sub>1</sub>, d<sub>2</sub>]</code> and <code>r = [r<sub>1</sub>, r<sub>2</sub>]</code>.</p>
+
+<p>Two delivery drones are tasked with completing a specific number of deliveries. Drone <code>i</code> must complete <code>d<sub>i</sub></code> deliveries.</p>
+
+<p>Each delivery takes <strong>exactly</strong> one hour and <strong>only one</strong> drone can make a delivery at any given hour.</p>
+
+<p>Additionally, both drones require recharging at specific intervals during which they cannot make deliveries. Drone <code>i</code> must recharge every <code>r<sub>i</sub></code> hours (i.e. at hours that are multiples of <code>r<sub>i</sub></code>).</p>
+
+<p>Return an integer denoting the <strong>minimum</strong> total time (in hours) required to complete all deliveries.</p>
