Technical/Programming content on Algorithms/Data structures

[ For Task - A ] /////////////////////// Task-A require to solve the coding problems. May you please send me the answer of any Two Sample question(See below A.1) with deliverable content/code items as defined in (See below A.2 /A2-1 to A 2-7) : ------------------------------------------- A.1 Sample Questions types: ------------------------------------------- [login to view URL] a function to print all of the permutations of a string. [login to view URL] a routine to draw a circle (x ** 2 + y ** 2 = r ** 2) without making use of any floating point computations at all. [login to view URL] an array of characters which form a sentence of words, give an efficient algorithm to reverse the order of the words (not characters) in it. [login to view URL] a very good method to count the number of ones in a 32 bit number. (caution: looping through testing each bit is not a solution). 5. Given two strings S1 and S2. Delete from S2 all those characters which occur in S1 also and finally create a clean S2 with the relevant characters deleted. --------------------------------------------------- A.2 Each Answer should contain the following: --------------------------------------------------- A.2-1: Assumptions/Limitations A.2-2: Pseudo code/Steps for the solution with appropriate text e.g. why this approach is chosen A.2-3: Major Data structures used to solve this problem e.g. why array used to solve this problem though linked list can be used A.2-4: Actual Code (Program) A-2-5: Output A-2-6: Set of unit test cases A-2-7 : Proper explanation wherever applicable [ For Task - B ] /////////////////////// Task B require to write a technical-writeup on algorithm topics , and that should be in very easy language and easily understandable. If interested in task B- then May you please send me a write-up on B.2/B.3 ( Concept with easiest examples ) Sample Topics : B.1 What about Algorithms? B.2 Sample write-up on Brute force Approach: B.3 Simple 100 words to 300 words explanation about divide and conquer ------- I have $1000 budget for Task-A/ $1000 Budget for Task-B. ( +/- are possible based on the type of work/quality/timely delivery) Please let me know If you have any further questions. /Sumit I prefer to work with people that have experience freelance writing and are online most of the work-day.
