Topological Sort

Topological sort is a sorting technique that sets up a hierarchy in a process. In this technique, when a directed network has nodes connected by arrows, the root node is placed before the successor node.

1. Big-O Notation Let f and g be functions from the set of integers or the set of real numbers to the set of real numbers. We say that f ( x ) is O ( g ( x ) ), read as "f ( x ) is big-oh of g ( x )", if there are constants C and k such that | f ( x ) | ≤ C | g ( x ) | whenever x > k. (a) Show that f(x) = x2 + 2x + 1 is O(x2) Solution: When x>1; ? 2 (1 + 2 ? + 1 ? 2 ) < ? 2 (1 + 2 1 + 1 1 2 ) = 4? 2 So, ??? ? > 1, ? 2 + 2? + 1 < 4? 2 From the definition 0 ≤ f(x) ≤ cg(x) for x≥1 Hence, for N0 = 1; c=4; and g(x)=x2 for N0 = 2; c=3; and g(x)=x2 for N0 = 3; c=2; and g(x)=x2 … Therefore, ? ? + ?? + ? = ?(? ? ) O(g(x)) = {f(x)|there exist positive constant c and N0 such that 0 ≤ f(x) ≤ cg(x) for all x≥N0} 2.

3. Unimodal Sequence Given n2 1, a sequence of n integers a[0],. . ., a[n-1] is unimodal if there exists t (with 0 st a[t+1] > . . . > a[n=1] The element a[t] is called the top of the sequence. For example, the sequence 1, 3, 5, 9, 4, 1 is unimodal, and its top is 9 (t = 3). Write a function get Toplndex_UnimodelSequence that takes a unimodal sequence & returns the index of the top of the sequence. The solution must have cost O(log(n)) in time in the worst case.

Let's call two numbers isomorphic if they have same number of digits and set of places having equal digits is same. We consider that all the numbers are in decimal notation and don't have leading zeroes. Consider some examples: • 12321 is isomorphic to 83538 and 45654. • 1232 is not isomorphically equal to 2342 because set of places having equal digits are {{1}, {2, 4}, {3}} and {{1, 4}, {2}, {3}} (digits are numbered from left to right using 1 based indexing). In other words, the digits order has to remain the same. • 12 isomorphic to 10,13,14, 92, but not isomorphic to 1, because their lengths are not equal and not isomorphic to 01, because leading zeroes are not allowed. Let F(X) denote the smallest integer (without leading zeroes) isomorphic to X where X is a positive integer. For example, F(12) = 10, F(213) = 102. You are given two integers N and M. Your task is to calculate F(1) % M + F(2) % M + F(3) % M + ... + F(N - 1) % M + F(N) % M.
