Binary search on 2 dimensional array
WebMar 9, 2007 · It is cool that there is a built-in binary search function in .NET but it only takes one dimensional arrays. If i could pass in the first dimension of the two dimensional array to the binarySearch function as a one dimensional array i think my problems would be solved. If this is just not possible can someone point me at some good code on the ... WebAnswer. The preconditions for Binary Search to be performed on a single dimensional array are: The array should be sorted, either in ascending order or descending order. Lower bound, upper bound and the sort order of the array must be known. Answered By. 2 Likes.
