I noticed there's a spelling error in an existing file (not related to my changes), but I've kept my PR focused solely on the BasicPrefixSum implementation to avoid scope creep.

My changes are limited to:

• PrefixSum/BasicPrefixSum.js
• PrefixSum/BasicPrefixSum.test.js

The spelling error appears to be in a pre-existing file and is unrelated to the prefix sum algorithm implementation. I can create a separate issue/PR to address that spelling error if needed, but wanted to keep this contribution focused on the specific issue #1783.

Thanks for reviewing! 🙏
