1: Finding a lost lion in the Sahara, binary search. Twenty questions games: finding out a 32-bit number, finding out a 32-bit number with at most one lie. Finding the MAX, the MIN, the MAXMIN. The optimality of the MAXMIN algorithm. Sorting with pairwise comparisons needs log (n!) steps.
2: Estimations of log (n!), Sorting, insertion-sort with $O(n\log n)$ comparisons, merging two sorted sequences of length n with 2n-1 comparisons, this is optimal. Merge sort. On average, also $\Omega(n\log n)$ comparisons are needed to sort n numbers.
