Maximum subarray problem
The maximum subarray problem is the task of finding the contiguous subarray within a one-dimensional array, a[1...n]
, of numbers which has the largest sum, where,
Example
The list usually contains both positive and negative numbers along with 0
. For example, for the array of values −2, 1, −3, 4, −1, 2, 1, −5, 4
the contiguous subarray with the largest sum is 4, −1, 2, 1
, with sum 6
.
