Parameter 'a' implicitly has an 'any' type when attempting to run the first exercise

[kqvanity]

when i try to run the first exercise, I get the following error messages

Found 2 errors in the same file, starting at: src/01-number.problem.ts:3

I've tried settings tsconfig.json's noImplicityAny' and strict` options to 'false' as advisable on the internet, but the error still persists. Any help?

The point of the exercise is to try and fix this error. When you fix the TS errors, the exercise will be marked as complete and you can continue to the next one!
