2594. Minimum Time to Repair Cars Medium

1/**
2 * [2594] Minimum Time to Repair Cars
3 *
4 * You are given an integer array ranks representing the ranks of some mechanics. <font face="monospace">ranksi</font> is the rank of the <font face="monospace">i^th</font> mechanic<font face="monospace">.</font> A mechanic with a rank r can repair <font face="monospace">n</font> cars in r * n^2 minutes.
5 * You are also given an integer cars representing the total number of cars waiting in the garage to be repaired.
6 * Return the minimum time taken to repair all the cars.
7 * Note: All the mechanics can repair the cars simultaneously.
8 *  
9 * <strong class="example">Example 1:
10 * 
11 * Input: ranks = [4,2,3,1], cars = 10
12 * Output: 16
13 * Explanation: 
14 * - The first mechanic will repair two cars. The time required is 4 * 2 * 2 = 16 minutes.
15 * - The second mechanic will repair two cars. The time required is 2 * 2 * 2 = 8 minutes.
16 * - The third mechanic will repair two cars. The time required is 3 * 2 * 2 = 12 minutes.
17 * - The fourth mechanic will repair four cars. The time required is 1 * 4 * 4 = 16 minutes.
18 * It can be proved that the cars cannot be repaired in less than 16 minutes.​​​​​
19 * 
20 * <strong class="example">Example 2:
21 * 
22 * Input: ranks = [5,1,8], cars = 6
23 * Output: 16
24 * Explanation: 
25 * - The first mechanic will repair one car. The time required is 5 * 1 * 1 = 5 minutes.
26 * - The second mechanic will repair four cars. The time required is 1 * 4 * 4 = 16 minutes.
27 * - The third mechanic will repair one car. The time required is 8 * 1 * 1 = 8 minutes.
28 * It can be proved that the cars cannot be repaired in less than 16 minutes.​​​​​
29 * 
30 *  
31 * Constraints:
32 * 
33 * 	1 <= ranks.length <= 10^5
34 * 	1 <= ranks[i] <= 100
35 * 	1 <= cars <= 10^6
