DAY 85 OF 90 · The loops under DSA

Same letters

Medium90 Days of Looping

Inputs

a and b are 0 to 12 lowercase letters (a to e).

Your tasks

Create a list counts of 26 zeros.
Use a loop over a to add 1 to each letter's count, then a loop over b to take 1 away.
Check that every count is 0.
Complete sameLetters so it returns true when b uses exactly the same letters as a, in any order, otherwise false. Return it, do not print it.

Example

With a = "listen" and b = "silent", sameLetters returns true.

Rules

Two empty texts match.

Test data

TEST DATA 1: a is "listen", b is "silent"

TEST DATA 2: a is "abc", b is "abd"

Practice focus

Prefix sums, counting, binary search, best stretch and sorting, all written as plain loops. This is where loops turn into named algorithms. You have already written the loops.
