34. Generating permutations

The chapter emphasizes the concept of backtracking, specifically focusing on generating permutations systematically. By understanding how to generate the next permutation of a sequence, the principles of searching for solutions in problems like the n-queens can be effectively applied. The process involves identifying patterns within sequences and ensuring that every possibility is explored efficiently.
