Explain the Big O time and space complexity of this code step by step, as if teaching a junior developer. Point out the most expensive part and how input size affects it. Code: [paste code]

Explain [data structure, e.g. a hash map / heap / trie] for a [level] developer. Include a text diagram, how operations work with time complexity, a clean implementation in [language], and when to use it in real projects.

This function is too slow for large inputs ([input size]). Analyse its time and space complexity, propose a more efficient approach, implement it, and show a quick benchmark plan. Code: [paste code]

Analyse the time and space complexity of this code. ``` [paste] ``` Explain the Big-O line by line in simple terms, identify the bottleneck, describe what happens with 10× and 1000× more data, and suggest a more efficient approach if one exists, with code.
