How to efficiently implement k Queues in a single array? - GeeksforGeeks



Create a data structure kQueues that represents k queues. Implementation of kQueues should use only one array, i.e., k queues should use the same array for storing elements. Following functions must be supported by kQueues.

enqueue(int x, int qn) –> adds x to queue number ‘qn’ where qn is from 0 to k-1

dequeue(int qn) –> deletes an element from queue number ‘qn’ where qn is from 0 to k-1

Analysis of Algorithm | Set 5 (Amortized Analysis Introduction) - GeeksforGeeks



Amortized Analysis (Link->http://ift.tt/1qIhw5l) is used for algorithms where an occasional operation is very slow, but most of the other operations are faster. In Amortized Analysis, we analyze a sequence of operations and guarantee a worst case average time which is lower than the worst case time of a particular expensive operation.

The example data structures whose operations are analyzed using Amortized Analysis are Hash Tables, Disjoint Sets and Splay Trees.

Idle Process: Finding Overlapping Rectangles in a given set of Axis aligned rectagles

Describe an algorithm that takes an unsorted array of axis-aligned rectangles and returns any pair of rectangles that overlaps, if there is such a pair. Axis-aligned means that all the rectangle sides are either parallel or perpendicular to the x- and y-axis. You can assume that each rectangle object has two variables in it: the x-y coordinates of the upper-left corner and the bottom-right corner.

Print All Combinations of a Number as a Sum of Candidate Numbers | LeetCode



Given a target number, and a series of candidate numbers, print out all combinations, so that the sum of candidate numbers equals to the target.



Here order is not important, so don’t print the duplicated combination.

e.g. target is 7, candidate is 2,3,6,7

output should be 7 and 3+2+2 (but not print 2+3+2, 2+2+3)

Pattern Searching | Set 6 (Efficient Construction of Finite Automata) - GeeksforGeeks

Algorithm:

1) Fill the first row. All entries in first row are always 0 except the entry for pat[0] character. For pat[0] character, we always need to go to state 1.

2) Initialize lps as 0. lps for the first index is always 0.

3) Do following for rows at index i = 1 to M. (M is the length of the pattern)

…..a) Copy the entries from the row at index equal to lps.

…..b) Update the entry for pat[i] character to i+1.

…..c) Update lps “lps = TF[lps][pat[i]]” where TF is the 2D array which is being constructed.

Longest Subarray with Sum Divisible by K | Algorithms Notes



Given an integer array A of length n and an integer K, design an O(n lg n) algorithm to find the longest subarray, subject to the sum of the subarray is divisible by K.

Solution:

Let S[i] be the sum of A[1..i], R[i] be S[i] % K. The sum of subarray A[i..j] = S[j] – S[i] is divisible by K if, and only if, R[i] = R[j]. Hence, we can sort R[i] and find the largest i – j, such that R[i] = R[j]. The total complexity is O(n lg n).
