Do steps 1 through 4 (excluding the computer program) of the engineering problem solving methodology for the following problem statement. Problem Statement: Calculate the area of the shaded region in the figure below in meters squared. (feet) 10 8 6 4 2 0 2 4 6 8 10 12 (feet) 14 16 18 Computer programming for C++ 1. Clearly and concisely state the problem that you were trying to solve. 2. Describe the input and output information of the problem. 3. Work the problem by hand. 4. Develop the algorithm and convert to computer program. Write a CFG for language L5 = { 0123x : x >= 1 and y >= 1}, over the alphabet = {0, 1, 2, 3). In other words, strings consisting of a clump of Os then a clump of 1s then a clump of 2s then a clump of 3s, where the length of the Os clump matches the 3s clump, and also the length of the 1s clump matches the 2s clump; you have at least one letter in each clump. For example, 0000123333 is a member where the Os and 3s are clumps of length x = 4, and the 1s and 2s are clumps of length y = 1. Hint: Generate the Os and the 3s first.
