City Distance Sorting
You are given a list of cities represented by their names and their Euclidean coordinates (x, y). Your task is to sort these cities by their distance from the origin (0, 0) in ascending order. In case of a tie in distance, sort them alphabetically by city name.
Input:
The first line contains an integer N (1 ≤ N ≤ 100) — the number of cities.
The next N lines each contain a string (city name, 1 ≤ len(name) ≤ 100) followed by two integers (x and y, -1000 ≤ x, y ≤ 1000).
Output:
Print the sorted list of cities in the format [[city1, x1, y1], [city2, x2, y2], ...].
Example:
Input:
3
CityA 1 2
CityB 2 1
CityC 1 1
Output:
[[CityC, 1, 1], [CityA, 1, 2], [CityB, 2, 1]]
