Sort Threats by Severity and Exploitability - Solution & Explanation

You are given a 2D integer array threats, where each threats[i] = [IDi, sevi​, expi]

• IDi: Unique identifier of the threat.
• sevi: Indicates the severity of the threat.
• expi: Indicates the exploitability of the threat.

The score of a threat i is defined as: score = 2 × sevi + expi

Your task is to return threats sorted in descending order of score.

If multiple threats have the same score, sort them by ascending ID​​​​​​​.

 

Example 1:

Example 2:

 

Constraints:

• 1 <= threats.length <= 105
• threats[i] == [IDi, sevi, expi]
• 1 <= IDi <= 106
• 1 <= sevi <= 109
• 1 <= expi <= 109
• All IDi are unique
