  2. 3SUM - Wikipedia

    en.wikipedia.org/wiki/3SUM

    In computational complexity theory, the 3SUM problem asks if a given set of real numbers contains three elements that sum to zero. A generalized version, k-SUM, asks the same question on k elements, rather than simply 3. 3SUM can be easily solved in () time, and matching (⌈ / ⌉) lower bounds are known in some specialized models of computation (Erickson 1999).

  3. Project Euler - Wikipedia

    en.wikipedia.org/wiki/Project_Euler

    The first Project Euler problem is Multiples of 3 and 5. If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000. It is a 5% rated problem, indicating it is one of the easiest on the site.

  4. 3-partition problem - Wikipedia

    en.wikipedia.org/wiki/3-partition_problem

    Conversely, in every solution of S u, since the target sum is 7 T and each element is in ( T /4, 7 T /2), there must be exactly 3 elements per set, so it corresponds to a solution of S r. The ABC-partition problem (also called numerical 3-d matching ) is a variant in which, instead of a set S with 3 m integers, there are three sets A , B , C ...

  5. Partition problem - Wikipedia

    en.wikipedia.org/wiki/Partition_problem

    Given S = {3,1,1,2,2,1}, a valid solution to the partition problem is the two sets S 1 = {1,1,1,2} and S 2 = {2,3}. Both sets sum to 5, and they partition S. Note that this solution is not unique. S 1 = {3,1,1} and S 2 = {2,2,1} is another solution. Not every multiset of positive integers has a partition into two subsets with equal sum.

  6. Subset sum problem - Wikipedia

    en.wikipedia.org/wiki/Subset_sum_problem

    Conversely, given a solution to the SubsetSumZero instance, it must contain the −T (since all integers in S are positive), so to get a sum of zero, it must also contain a subset of S with a sum of +T, which is a solution of the SubsetSumPositive instance. The input integers are positive, and T = sum(S)/2.

  7. Maximum subarray problem - Wikipedia

    en.wikipedia.org/wiki/Maximum_subarray_problem

    Each possible contiguous sub-array is represented by a point on a colored line. That point's y-coordinate represents the sum of the sample. Its x-coordinate represents the end of the sample, and the leftmost point on that colored line represents the start of the sample. In this case, the array from which samples are taken is [2, 3, -1, -20, 5, 10].
