Re: [algogeeks] 4Sum
Its simple varition of 3 sum problem , using hask table u can easily do it . let s=a+b+c+d can be written as b+c+d=s-a; - 3 SUM Try it let me know i find any difficulty :) On Fri, Jun 15, 2012 at 3:50 PM, Akshat Sapra sapraaks...@gmail.com wrote: Given an array *S* of *n* integers, are there elements *a*, *b*, *c*, and *d* in *S* such that *a* + *b* + *c* + *d* = target?

Re: [algogeeks] Re: Maximal possible subsets Algorithm
@piyuesh 3-Sum is not exponential ? its quadratic , check wiki for refrence ? On Mon, Dec 5, 2011 at 5:36 PM, Piyush Grover piyush4u.iit...@gmail.comwrote: As I mentioned earlier solution with exponential time-complexity is the obvious one. Is there any way to solve this problem by greedy/Dynamic algo? On Mon, Dec 5, 2011 at 5:24 PM, WgpShashank shashank7andr...@gmail.comwrote: @piyuesh , Saurabh isn't 3-Sum Suffics Here ? Another thought problem can also be thought by generating power set of given set e.g. if set has n elemnts its power set has 2^n elements , then finds the set that has sum up yo given weight isn't it ? hope you know how to find power set efficiently ? correct if is missed anything ?

Re: [algogeeks] Re: Jumping Puzzle
HI Rohit, Although i haven't checked test many cases also I am not saying algo is wrong but DP will always Gives us Optimal Solution, even for large data-set,but Greedy Will Fail in That Case.I was aware of the same Greedy Algo/Code That you posted but found DP Will Excite Interviewer :) Regards Shashank Mani Computer Science Is Awesome So Why I Write Code Computer Science Birla institute of Technology Mesra On Sat, Aug 13, 2011 at 11:08 PM, rohit jangid rohit.nsi...@gmail.comwrote: ok check this, https://ideone.com/hZboG there may be bugs in coding, but I'm quite sure that algo is correct need to check more cases though but working on all the cases discussed here is there any proof that greedy won't work in this case?
