1. (Shortest Path) Please find the shortest path between the blue triangle and red tri- angle as Figure 1. Please explain your approach and develop the computationally efficient algorithm to get the results. Can you obtain (or estimate) the time com- plexity and memory complexity of your algorithm? 麗

(c) A palindromic number is a number that is the same if read forwards or backwards: 12321 and 641146 are examples. It is possible to represent a number using an array of digits (numbers 0- 9), for example: [1,9,5, 2] could represent 1952. i. Using an appropriate iteration construct, write an algorithm as a procedure that decides if an input array A[1..n] of digits is a palindromic number.

(Q4) Problem 1.41 from the Baase’s textbook, page 65: Write out the algorithm to find K in the ordered array by the method suggested in the text (Section 1.6) that compares K to every fourth entry until K itself or an entry larger than K is found, and then, in the latter case, searches for K among the preceding three. How many comparisons does your algorithm do in the worst case?

Solution Summary: The author explains how the array padding transformation reduces memory system conflicts. The padding eliminates the conflict-misses and only three-fourth of the references are hits.
