You are given a set of ABC cubes for kids (like the one shown below) and a word. On each side of each cube a letter is written. 4. 0 You need to find out, is it possible to form a given word by the cubes? For example, suppose that you have 5 cubes: B1: MXTUAS B2: O QATGE ??: REwMNA B4: M BDFAC ?5: IJKGDE (here for each cube the list of letters written on its sides is given) You can write the word "MAMA" using cubes B3, B2, B4, B1; B3 82 84 B1 At the same time, you cannot form the word "SUN". You have all 3 letters "S", "U" and "N" on the cubes but the letters "S" and "U" are on the same cube B1, and you cannot use it twice Represent this problem as an algorithmic problem. What is this algorithmic problem? Is it possible to solve it in a polynomial time
