Yesterday was Animesh's best friend's (at least he thinks so) birthday. Animesh had bought a nice present for her, but she didn't even invite Animesh :-( . He came to know that only the people who have the secret key for the birthday party can get the invitation the party. Unfortunately Animesh does not have that key, but he know that the key can be found here. Can you help Animesh find the key so that he can attend her birthday party and give her the sweetest present he bought for her.
