== Erroneous Examples ==

Many of the examples initialize the maximum subarray sum to 0. This produces erroneous results if the maximum subarray total is negative. The maximum subarray should be initialized to the most negative integer value available for each language.--[[User:Waldorf|Waldorf]] 16:37, 29 December 2007 (MST)

The statement that a zero length array will produce a sum of 0 is nonsense. 0 is a valid sum. A zero length array cannot have a sum. All solutions should provide a valid representation for a zero length array as an input to the maximum subarray calculation. The zero length subarray should be reported as an exceptional (or erroneous) condition.--[[User:Waldorf|Waldorf]] 21:20, 29 December 2007 (MST)
