Problem 4. [25 pts] [PlacingTokens] We have a grid M of size nxn where each cell is either White or Black. Describe a polynomial- time algorithm to place token on the grid using network flows such that the following two conditions are met: 1. Every token is placed on a white cell 2. Each row and each column of the grid has exactly one token See the example of a valid placement of tokens on the Figure 1. The algorithm should detect if no such placement exists.
