35. Alice and Bob play the following coins-on-a-stack game. 20 coins are stacked one above the other. One of them is a special (gold) coin and the rest are ordinary coins. The goal is to bring the gold coin to the top by repeatedly moving the topmost coin to another position in the stack. Alice starts and the players take turns. A turn consists of moving the coin on the top to a position i below the top coin (0 = i = 20). We will call this an i-move (thus a 0-move implies doing nothing). The proviso is that an i-move cannot be repeated; for example once a player makes a 2-move, on subsequent turns neither player can make a 2-move. If the gold coin happens to be on top when it's a player's turn then the player wins the game. Initially, the gold coinis the third coin from the top. Then
(a) In order to win, Alice's first move should be a 1-move
(b) In order to win, Alice's first move should be a 0-move
(c) In order to win, Alice's first move can be a 0-move or a 1-move
(d) Alice has no winning strategy
I attempted 29 out of 35 and results were declared in about an hour or so and i cleared the test.
In our college around 330 appeared for the apti out of which 270 cleared the written test. Interview was held on 30th December 2010, at Techno India Salt LAKE campus. The reporting time for us was at 2.30 p.m. When my turn for in interview came it was 5.40 p.m.
My interview went on for around 20 minutes. My name was called by some TCS official and I went inside along with him inside the room. The room where I was interviewed there was 3 interviewer simultaneously interviewing my friends as that slot was especially for our college only. So I went near to him.
To be honest i was nervous and my heart was pounding. I said good evening Sir. Then i sat on the chair. Then he was looking throughly through the TCS form which is to be filled and submitted along with my CV. After couple of minutes he asked me
Tell me about yourself? I mentioned my name, native place, education and hobbies. As I mentioned my hobbies as internet surfing and chating. He asked what I luck about chating? Why I spent time in chating rather than reading the books? I'm very passionate about chating so I replayed to him in a manner I guess he liked it.
Then he went over to my project- my project title "jChat-Chat Client in Java". He asked all the details about the project then he carried on asked to draw the architecture of the project and database part too. Basically J stands for Java. It is basically intranet chat application which is being developed by me as a part of my final year project.
Then he asked me about the keys in DBMS: Primary key its features, foreign key. Constraints different types of constraints. Well in my subject of interest I had mentioned operating system and networking but no questions from this two subjects. After that he said we will get bak to you then said said thank you sir have a nice day and left the room.
Anyways I would like to thank God and all those who helped me in paving the path for me. Remember 2 thing in apti dont guess and in interview be relaxed. Another thing your are not out unless and until the result is out even if your out here don't wry as because TCS is not the last company so have faith in God. If anything you wish 2 know just mail me or give me call. If I can I will surely help you.
Last but not the least I would like to thank Freshersworld.com for their effort. Its an amazing site for a freshers. He can avail the info from here.
Thank You.
