    My python Code

    if __name__ == '__main__':
        x = int(input())
        y = int(input())
        z = int(input())
        n = int(input())
        
        liste = []
        for i in range(0,x+1):
            for j in range(0,y+1):
                for k in range(0,z+1):
                    if (i + j + k) != n:
                        liste.append([i,j,k])
                        
        print(liste)
