Question 3. [20 marks] In this question, we are given a checkerboard with a missing cell (denoted by \"0\"), and we are asked to tile it by using triominoes. An example is provided in Figure 1. A triomino can be arranged as one of the followings. (a) before tiling (b) after tiling Figure 1. An example of tiling a checkerboard with a missing cell 3(a) Now, we are given the following 8x8 checkerboard with a missing cell (\"07). Draw the checkerboard after dividing it into 4 sub-checkerboards such that: e each sub-checkerboard is a square, and e cach sub-checkerboard contains exactly either a missing cell (\"0) or a cell covered by a triomino. Hint: Place a triomino at a suitable location to divide the checkerboard
