If atleast one odd value is available in the sequence ,then first will win the game. Otherwise , second will win.

EXPLAINATIN:
In optimal case , the current player will always try to make all the values in the sequence even. If there is one or more odd value(s) present in the sequence, then I will take 1 from each to make them even. This will leave all even values for the second player. This forces second player to take atleast 1 from the even values. It again gives me chance to pick one from the odds. At last there will be atleast one 1 for me to choose . And I will win the game.
