Strange Printer II SOLUTION Biweekly Contest 35
There is an unusual printer with the accompanying two extraordinary prerequisites:
On each turn, the printer will print a strong rectangular example of a solitary shading on the matrix. This will conceal the current hues in the square shape.
When the printer has utilized a shading for the above activity, a similar shading can’t be utilized once more.
You are given a m x n lattice targetGrid, where targetGrid[row][col] is the shading in the position (line, col) of the network.
Return valid in the event that it is conceivable to print the lattice targetGrid, in any case, return bogus.
Model 1:
Info: targetGrid = [[1,1,1,1],[1,2,2,1],[1,2,2,1],[1,1,1,1]]
Yield: valid
Model 2:
Info: targetGrid = [[1,1,1,1],[1,1,3,3],[1,1,3,4],[5,5,1,4]]
Yield: valid
Model 3:
Info: targetGrid = [[1,2,1],[2,1,2],[1,2,1]]
Yield: bogus
Clarification: It is difficult to shape targetGrid on the grounds that it isn’t permitted to print similar shading in various turns.
Model 4:
Information: targetGrid = [[1,1,1],[3,1,3]]
Yield: bogus
Requirements:
m == targetGrid.length
n == targetGrid[i].length
1 <= m, n <= 60
1 <= targetGrid[row][col] <= 60
