I assume this is because of an anti-pattern side-effect. I get keyboard input from the user and use it to modify the state. I recently switched to useReducer from useState hooks because of a growing complex state. It worked great with useState hooks. Every keyboard input is printed to the screen multiple times. But none keyboard modification to the state (changes to state not from event handler), does not show multiple renders.

Problem

Let's say result is a 2D array and values is a 1D array. values holds some values associated with each element in result. The mapping of an element in values to result is stored in x_mapping and y_mapping. A position in result can be associated with different values. (x,y) pair from x_mapping and y_mapping is associated with results[-y,x]. I have to find the unique count of the values grouped by associations.

An example for better clarification.
