Problem Statement

Wall Painting Combinations Problem Description Sonya is an artist tasked with painting a mural in an environmentally sensitive area. Due to strict environmental regulations, certain paints can be used on specific sections of the wall while others cannot. Sonya needs to ensure that the entire mural is painted while adhering to these constraints. Given N sections on wall and M paint types, you're provided with a list of environmental constraints (1 for allowed, 0 for restricted) for each paint type and a set of available paint types for each section. The goal is to find how many valid combinations of paint she can use to cover all sections of the wall without violating any environmental regulations. Input Format The first line contains an integer N represent the number of sections on the wall. The second line contains an integer M represent the number of paint types. The third line contains M space-separated integers where 1 means the paint type is allowed and 0 means it is restricted. T
