Analyzing Time Complexity in Code

The video tutorial explains how to determine the time complexity of a code snippet with nested loops. The outer loop runs n times, while the inner loop updates by powers of two and terminates when it reaches n. The inner loop's time complexity is calculated as log log n. By multiplying the complexities of the outer and inner loops, the overall time complexity is determined to be n log log n.

What is the main task described in the video regarding the code snippet?

• To translate the code into another programming language

• To find the syntax errors in the code

• To optimize the code for better performance

• To determine the time complexity of the code
