-This repository contains answers to the assignments of Advent of Coding 2022
+# Advent of Code 2022 - assignment 1
+This is the first assignment for Advent of Code 2022. The provided solution uses 3 variables: currentScore, highestCalorieScore, currentElf, highestElf.
+It is complexity O(n²) since it loops through every line exactly once and the iterates for recalculating highscore.
+
+## Solution description
+Every iteration the score is added to the currentScore. If an empty line is detected we check if currentscore exceeds one of our highestCalorieScore, if yes we assign currentElf to highestElf.
