Step 1: I began by reading the total number of games (N) and then the list of results, where each element indicates whether TEAM A or TEAM B won that particular game.

Step 2: Since the problem only required counting wins, I decided to use a brute force approach. I iterated through the list and maintained two counters—one for TEAM A and one for TEAM B.

Step 3: For each game result, I incremented the corresponding counter. This allowed me to directly count how many wins each team had.

Step 4: After processing all the game results, I compared the two counters. If TEAM A’s counter was higher, I concluded that TEAM A won the overall matchup. If TEAM B’s counter was higher, TEAM B was the winner. If both counters were equal, I returned "Draw".

Step 5: I then output the result. The brute force method was sufficient here because the time complexity of O(N) was acceptable given the problem constraints.

Step 1: I started by reading the input integer.
Step 2: I converted the integer into its binary form. In many languages, this can be done using built-in functions (for example, using bin() in Python or bitwise operations).
Step 3: Once I had the binary representation as a string, I iterated over each character in the string and counted the occurrences of '1'.
Step 4: The final step was to return or print the count of ones..

Tip: Thoroughly study Operating System Concepts by Galvin to understand key OS topics like semaphores and memory management.

Tip 1: Practice SQL queries, as database-related questions that are commonly asked.
Tip 2: Be clear and structured in your explanations, as this is a video call round, and communication skills matter.
