Given a chunk size of 1000 characters and a document of 2500 characters, how many chunks will Langchain create (assuming no overlap)?
A5
B2
C4
D3
Step-by-Step Solution
Solution:

  1. Step 1: Calculate number of chunks by dividing document length by chunk size

    2500 characters divided by 1000 characters per chunk equals 2.5 chunks.

  2. Step 2: Round up to cover entire document

    Since partial chunks count, round 2.5 up to 3 chunks.

  3. Final Answer:

    3 -> Option D

  4. Quick Check:

    Chunks count = A [OK]
Quick Trick: Divide length by chunk size, round up for total chunks [OK]
Common Mistakes:
  • Rounding down instead of up
  • Ignoring partial last chunk
  • Assuming overlap affects chunk count here
