@kaushikjatin You are given an array of number, Vikrant and Kunal now start playing a game using that array.
Rules of the game are: Vikrant can pick any available number. Let say he picks a
He will get points for the number = frequency_of_number* number
And all the occurences of the picked number will be removed.
Now Kunal will remove all the occurrence of a-1 and a+1 (if present).

Now vikrant again will pick a number from the remaining array and whole process will repeat till no elements are left.
eg array is 4 1 0 1 1 2 3 3 4 0 4
Now if Vikrant picks 4.
Score= 4 * fre_of_4= 4*3=12
Now the array is (4 removed)
1 0 1 1 2 3 3 0
Now kunal will remove a-1(4-1=3) and a+1(4+1=5). Now array becomes
1 0 1 1 2 0 (as only 3 is present we remove it)

Now its turn of Vik again
He picks 1
new array
0 2
score=1*3
accumulated score= prev_score+score=3+12=15
kunal removes 0(1-1) and 2(1+1)
now no element left game ends.
final score is 15.

We need to maximize the final score.
If this resolves your doubt mark it as resolved.
