Triple SumsProblem code: TSUM You‘re given a sequencesofNdistinct integers.Consider all the possible sums of three integers from the sequence at three different indicies.For each obtainable sum output the number of different triples of indicies that generate it.Constraints:N Input The first line of input contains a single integer N.Each of the next N lines contain an element of s.O

Controlling Companies Some companies is partial owners of other companies because they has acquired part of their total shares of stock. For example, Ford owns 12% of Mazda. It is said, a company A, controls company B if at least one of the following conditions is satisfied: Company A = Company B Company A owns more than 50% of company B Company A Controls K (k >= 1) Companies denoted C1, ..., CK with all company Ci owning xi% of the company B and X1 + .... + XK > 50%.

hash cannot store the same element because the same element has the same hash value. If the array {2,5,6} is evaluated for target=4, there is no solution, and the array {2,2,5,6},target=4 has a solution. How do I deal with this situation? It can be reversed, the initial hash is empty, and the elements that have been traversed are gradually added to the hash.2) Three number and (3 sum)Topic ID: 57, Link: http://www.lintcode.com/zh-cn/problem/3sum/Title Description: Give an array of n integers, f

The representation of a ternary group(1), the purpose: for the large sparse matrix in the actual problem, if the conventional allocation method in the computer storage, will generate a lot of memory waste, and in the access and operation of the time will also cause a lot of waste of time, in order to solve this problem, so good to produce a variety of solutions.(2) Because of its sparse characteristics, the memory cost of sparse matrix can be greatly saved by compressing. This method can save st

Given an array nums containing n integers, determine if there are three element a,b,c in the nums, making a + B + c = 0. Find all triples that satisfy the condition and do not repeat. Note: You cannot include duplicate triples in the answer. For example, given an array of nums = [-1, 0, 1, 2,-1,-4], the set of triples that satisfies the requirement is: [ [-1,

for each non-0 element, such as the row and column number where it resides, can accurately reflect the location of the element. Implementation method: Each non-0 element is represented by a ternary group (I,J,AIJ), and each sparse matrix can be represented by a ternary table. Each non-0 element in a sparse matrix is represented as: (line number, column number, non-0 element value)-Ternary Group table: a set of triples consisting of non-0 elements of

sizes (modulo) to M, and they form a circle. The 0 vector is also the only vector without a direction. 2, Negative vector Negative operators can also be applied to vectors. Each vector v has an additive inverse-V, whose dimensions and V satisfy v+ (-V) = 0. In order to get the negative vectors of any dimension vector, we simply have to turn each component of the vector into a negative one. Geometric interpretation: Negative to the vector, you will get a vector of equal size an
