Implement and analyze number-pattern function
Problem Description
Implement a function, print_number_lines(n), that generates n lines of output. For each line i (from 1 to n), the function should print the integers from 1 up to i, with each number separated by a single space.
For example, if n=3, the output should be:
1
1 2
1 2 3
Requirements
In addition to implementing the function, you must:
- Complexity Analysis: Analyze the time and auxiliary space complexity for two distinct approaches:
- Print-as-you-go: Each line is printed immediately as it's generated.
- Build-then-print: All lines are first generated and stored (e.g., in a list of strings), and then printed at the very end.
- Off-by-One Pitfalls: Describe common off-by-one errors that might occur during the implementation of such a pattern generation.
- Alternative Return Type: Provide a modified version of the function that, instead of printing, returns a list of strings, where each string represents a line of the generated pattern.

Optimizing resource usage (time and auxiliary space) for string generation and I/O operations, considering the trade-offs between immediate output and buffered output, while ensuring correctness for common indexing and loop boundary conditions.
