What is a code to find the winner of game of removing array elements having GCD equal to 1 and the other steps required given the following:
Find the winner of game of removing array elements having GCD equal to 1 | Function to find the winner of the game by removing array elements whose GCD is 1.
mp [ i ] : Stores count of array elements whose prime factor is i.
Traverse the array.
Calculate the prime factors of arr [ i ].
If arr [ i ] is divisible by j.
Update mp [ j ].
Update arr [ i ].
If arr [ i ] exceeds 1.
Stores maximum value present in the Map.
Traverse the map.
Update maxCnt.
If n is an even number.
If maxCnt is greater than or equal to n - 1.
Player 1 wins.
Player 2 wins.
If maxCnt equal to n.
Player 1 wins.
Player 2 wins.
