Problem 3. Consider finite strings over the alphabet Σ = {a, b, c, d}. The power operation represents string repetition, for example a 3 b 4 c denotes the string aaac. Define a contextfree grammar G generating the language L(G) = {w|(∃i, j, k)w = a i b (i+j+k) c jd k}, the set of words where the number of b’s is the same as the number of all other letters together and the letters are ordered alphabetically.
