The speaker begins by illustrating how programmers approach problems differently from humans, using the example of counting 9-digit numbers formed from digits 1-9 without repetition []. While a human might use factorial logic, a programmer would break it down into smaller, iterative steps, building from 1-digit numbers up to 9-digit numbers. This process, shown in the code at [], is essentially calculating factorial but demonstrates a constructive, step-by-step problem-solving method rather than a direct mathematical formula.
