You have to perform the following operation N/2 times:
1. Select nums, nums; such that (i+j) from the list
2. Take their bitwise OR, add the value of the least significant set bit to the score
3. Delete those two numbers
If the selected numbers are 5=(101)2 and 7=(111)2 then the bitwise OR of the two numbers is 7=(111)2. So, the least significant bit of 7 1.e. 1= (001), will be added to the current score.
Notes
• H-based indexing is followed
• A bitwise OR is a binary operation that takes two bit patterns of equal length and performs the logical inclusive OR operation on each
pair of corresponding bits. The result in each position is O if both bits are 0, while otherwise, the result is 1.
Strings in 02 denote the binary representation.
Task
- 100.0
Print the maximum possible score.
Example
100.0
Assumptions
•
N-4
• nums = [1,2.1.4)
Approach
. For the given case pairing (1, 1), (2, 4) that is (nums/1), nums[3]), (nums[2],,nums[4]) with 1-based indexing results in a maximum score of
3. pairing like (4,1),(1, 2) that is (nums[4], nums/1). (nums(3), nums[2]) results in 2.
Hence, the answer is 3.
