Explain how a hash map works internally, including collision handling
A hash map stores key-value pairs by computing a hash of the key to determine which 'bucket' (array index) the pair belongs in. When you insert a key, the hash function converts it to an integer, which is then mapped to an index via modulo with the array size. Collisions—when two keys map to the same index—are handled through chaining (storing a linked list at each bucket) or open addressing (probing for the next empty slot). Load factor triggers resizing: when the ratio of entries to buckets exceeds a threshold (typically 0.75), the array doubles in size and all entries are rehashed.
Translate this Chinese proverb and explain its meaning: 三人行，必有我师焉
Translation: 'Among three people walking together, there must be one who can be my teacher.' This proverb comes from Confucius' Analerta (Lunyu) and conveys that everyone you meet has something valuable to teach you. It encourages humility and lifelong learning—no matter how knowledgeable you are, others possess skills, perspectives, or experiences worth learning from. It's a cornerstone of Chinese educational philosophy.
