-## 题目描述
-
-
-
-You are given an integer array timeReq and an integer splitTime.
-
-In the microscopic world of the human body, the immune system faces an extraordinary challenge: combatting a rapidly multiplying bacterial colony that threatens the body's survival.
-
-Initially, only one white blood cell (WBC) is deployed to eliminate the bacteria. However, the lone WBC quickly realizes it cannot keep up with the bacterial growth rate.
-
-The WBC devises a clever strategy to fight the bacteria:
-
-
- - The
ith bacterial strain takes timeReq[i] units of time to be eliminated.
- - A single WBC can eliminate only one bacterial strain. Afterwards, the WBC is exhausted and cannot perform any other tasks.
- - A WBC can split itself into two WBCs, but this requires
splitTime units of time. Once split, the two WBCs can work in parallel on eliminating the bacteria.
- - Only one WBC can work on a single bacterial strain. Multiple WBCs cannot attack one strain in parallel.
-
-
-You must determine the minimum time required to eliminate all the bacterial strains.
-
-Note that the bacterial strains can be eliminated in any order.
-
-
-Example 1:
-
-
-
Input: timeReq = [10,4,5], splitTime = 2
-
-
Output: 12
-
-
Explanation:
-
-
The elimination process goes as follows:
-
-
- - Initially, there is a single WBC. The WBC splits into 2 WBCs after 2 units of time.
- - One of the WBCs eliminates strain 0 at a time
t = 2 + 10 = 12. The other WBC splits again, using 2 units of time.
- - The 2 new WBCs eliminate the bacteria at times
t = 2 + 2 + 4 and t = 2 + 2 + 5.
-
-
Example 2:
-
-
-
Input: timeReq = [10,4], splitTime = 5
-
-
Output:15
-
-
Explanation:
-
-
The elimination process goes as follows:
-
-
- - Initially, there is a single WBC. The WBC splits into 2 WBCs after 5 units of time.
- - The 2 new WBCs eliminate the bacteria at times
t = 5 + 10 and t = 5 + 4.
-
-
-Constraints:
-
-
- 2 <= timeReq.length <= 1051 <= timeReq[i] <= 1091 <= splitTime <= 109
