ADDITIONAL SYSTEM INFORMATION :
suggested code is for all runtimes, all environments.

A DESCRIPTION OF THE PROBLEM :
Currently Math.max(...) and Math.min(...) support two parameters. The looks like below:
public static int max(int a, int b) {
  return a > b ? a : b;
}

I suggest it be changed to:

public static int max(int... nums) {
   int result = nums[0];
   for(int num : nums) {
      result = result > num ? result : num;
   }
   return result;
}

and similar code for Math.min(...).

This will greatly help in coding challenges where min/max needs to be computed of more than 2 numbers, and since this code is backwards compatible, it will not required any changes to old code.
