스카이스크래퍼 빌딩 퍼즐 - 고난도 변형 스도쿠

Skyscrapers is a puzzle that thinks of different numbers as the height of the building and solves them according to the given conditions.

It looks similar to Sudoku, but it is a puzzle with a unique concept in that it considers the numbers as buildings that are that high.

1. In a square made up of n horizontal and n vertical, each number from 1 to n is entered only once.
2. The number inside the square indicates the height of the building, and the number outside the square indicates the number of buildings visible from the location.

Consider the size and relative position of the numbers to complete the puzzle!
