5. Show how you can sort n integers in the range 0 to (n - 1) in O(n). For example, you can have n = 10000 integers in the range 0 to 99999999 = 10000-1 Hint: Use the idea from Radix-Sort 6. The square of a directed graph G = (V, E) is the graph G2 = (V, E2) such that uw E if and only if for some v V, both uv and vw E. Design an algorithm (and write pseudo-code) for computing G from a graph G given with an adjacency-matrix representation. Analyze the running time complexity of your algorithm.
