Will Brute force solution works here? What will be its complexity?
Brute force definitely won't work here. Think of some simple solution. Take some example and make some observations.
Will order of nuts traversed by squirrel is important or only first nut traversed by squirrel is important?
Are there some paths which squirrel have to cover in any case? If yes, what are they?
Did you notice only first nut traversed by squirrel matters? Obviously squirrel will choose first nut which will result in minimum distance.

Problems like Squirrel Simulation are representative of interview questions that test mathematical reasoning and greedy optimization. While the exact question may vary, similar grid distance and optimization problems are common in technical interviews.
Only simple arrays and basic variables are needed. The nuts are processed sequentially, so no advanced data structures are required beyond iterating through the list of nut coordinates.
The optimal approach uses a greedy observation based on Manhattan distance. First compute the round-trip distance from the tree to every nut, then adjust the total by selecting the nut that gives the maximum distance advantage when collected first by the squirrel.
The grid movement in the problem is restricted to horizontal and vertical steps. Because of this, the Manhattan distance formula correctly represents the shortest path between two positions on the grid.
