[algogeeks] Minimum sum of Array
Hello All! I have a given array of numbers and I have to change the sign of numbers to find out the minimum sum. The minimum sum will be 0 or greater than 0. Here is couple of test cases 1. [ 1 , 2 , 3 , 2 , 4 ]. Changing the sign [ -1 , -2 , -3 , 2 , 4 ] so minimum sum will be 0. 2. [ 3 , 5 , 7 , 11 , 13 ]. Changing the sign [ -3 , -5 , 7 , -11 , 13 ] so minimum sum is 1. So technically this problem boils down to divide the set into two subset and find out the minimum difference. I though of DP but the number of element in array could 10^5 so could some one please tell me how to solve this problem ? I didn't assume that number will be positive because it was not given in the problem. Regards Mukesh Tiwari --

What you explained is the property of Treap data structure . You can have a look at wiki [ http://en.wikipedia.org/wiki/Treap ] or you can search google for treap.

It has the heap property if, for every node, the keys of its children are all smaller than its own key. You are given a set of n binary tree nodes that each contain an integer i and an integer j. No two i values are equal and no two j values are equal. We must assemble the nodes into a single binary tree where the i values obey the BST property and the j values obey the heap property. If you pay attention only to the second key in each node, the tree looks like a heap, and if you pay attention only to the first key in each node, it looks like a binary search tree.Describe a recursive algorithm for assembling such a tree -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

Hello everybody , i am trying to solve this(http://online- judge.uva.es/ p/v9/903.html) problem and input constrants are such that it is not possible to store the the numbers in the array and print those numbers. So i use the algorithm 1)get the number and return its coordinate 2) take the input all adjacent coordiantes and return the number belonging to that coordinate . i am facing the problem in second part that is if i have given coordiante how to get the number belonging to that coordinate, lets consider the spiral 21 22 23 24 25 26 20 7 8 9 10 19 6 1 2 11 18 5 4 3 12 17 16 15 14 13 let the coordinate of 1 is (0,0) ie origin then coordinate of 11 will be (2,0) and so on . now my problem is if i give coordiante (2,-1) then my program should return 12 . thnkx in advance --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

[algogeeks] Re: Sum of Gaussian factor
ya you are right . this is project euler problem . until now i have found that i can determine how many devisiors of number in sqrt(n) but what are the divisiors above aqrt(n) i am not able to determine. if sqrt(n) is perfect square and there are k factors upto sqrt(n) then total number of divisiors will be (2*k-1) otherwise (2*k). i.e.25 is perfect squre and sqrt(25)=5 .There are only two divisiors 1 and 5 then total number of divisiors of 25 will (2*2-1)=3 but here problem arise . after sqrt(n) i can not find what will be other factors . if some how i can over come this problem than for each divisior of number i have to find out all the prime factors and check out how many of them are in form of 4k+1 and how many are of 4k+3 . for all 4k +1 prime numbers i have to find p=a^2+b^2. but still i don't know how much it will be efficient becoz till now i haven't coded this problem .

I'm sure you already note that if a+bi is a factor, then a-bi is also a factor, and similiarly when a != b, b-ai and b+ai are also Gaussian factors.

[algogeeks] problem regarding lexicographic path
hi friends i am try to solving this question http://online-judge.uva.es/p/v1/116.html for this problem i use left to right dynamic programming so i m getting the total minimum cost but i m not getting how to find out lexicographically shortest path .here is my code .if u can change it fine but plz suggest me algorithm to find lexicographically shortest path. my program works fine if one path exist but if more than one path exist then it's not giving lexicographically smallest path.what i m doing is i m finding last column(n-1) minimum value and note down the row number (let it be i).now in second last column(n-2) i searched out minmium value in row i-1,i and i+1 becoz of problem property. and i keep doing this until i reach the 0th column.doing this i m not getting what i suppose to find out ...lexicographically smallest path.plz help... #includestdio.h int min1(int k,int m,int n) { int min; min=k; if(minm) min=m; if(minn) min=n; return(min); } main() { int m1[100][100],a[100][100],i,j,m,n,min,k,arr[100],t,min2,t1,t2,t3; while(scanf(%d%d,m,n)==2) { for(i=0;im;i++) for(j=0;jn;j++) scanf(%d,a[i][j]); for(i=0;im;i++) m1[i][0]=a[i][0]; for(j=1;jn;j++) for(i=0;im;i++) m1[i][j]=a[i][j]+min1(m1[(i+m-1)%m][j-1],m1[i][j-1],m1[(i+1)%m][j-1]); /*for(i=0;im;i++) { for(j=0;jn;j++) printf(%d ,m1[i][j]); printf(\n); }*/ //printf(\n); min2=m1[0][n-1]; k=0; for(i=1;im;i++) if(m1[i][n-1]min2) { min2=m1[i][n-1]; k=i; } //printf(k=%d min=%d\n,k+1,min2); arr[n-1]=k; for(j=n-2;j=0;j--) { min=m1[(arr[j+1]+m-1)%m][j]; t=(arr[j+1]+m-1)%m; if(minm1[arr[j+1]][j]) { min=m1[arr[j+1]][j]; t=arr[j+1]; } if(minm1[(arr[j+1]+1)%m][j]) { min=m1[(arr[j+1]+1)%m][j]; t=(arr[j+1]+1)%m; } arr[j]=t; //printf(min=%d arr[%d]=%d\n,min,j,t); } for(i=0;i=n-1;i++) printf(%d ,arr[i]+1); printf(\n%d\n,min2); } } --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Algorithm Geeks group.
