Types of Hash Functions in C

Types of Hash Functions in C is a DSA topic. In plain words you use it for name → phone in a diary. Don’t start with a slogan — start with that picture.

Smallest example: key % size + collision plan. Type it, run it, and say what you see. If you can do that from memory, you know Types of Hash Functions in C.

From the example next to this theory: Types of Hash Functions in C — hash maps give average O(1) insert/lookup — dict in Python.

Trap — bad hash → pile-up. Fix that before you talk about advanced DSA.

Viva — what is Types of Hash Functions in C? Then show key % size + collision plan. Then name the trap.

Exam tip

What is Types of Hash Functions in C? Show this: key % size + collision plan. Trap: bad hash → pile-up.

Example

freq = {}
for ch in "banana":
    freq[ch] = freq.get(ch, 0) + 1
print(freq)
print(freq.get("a"), freq.get("z", 0))
