Encrypted Skyscrapers：

1. Fill in a number from 1-5 in each grid, and make each row and column have no repeated numbers;
2. Each Chinese character represents a number, the character inside the plate is equal to the number filled in the grid, and the character outside the plate is equal to the observed number of skyscrapers at that location;
3. For the same color, the same word represents the same number, and different words represent different numbers;
4. There is no correlation between words of different colors.

Standard Skyscrapers:

Insert a digit from 1 to N into each cell in the N by N grid so that no digit repeats in any row or column. Also, each number in the grid represents the height of a building and the clues on the outside of the grid indicate how many buildings can be “seen” when looking from that direction. Taller buildings block the view of smaller buildings.
