an `O(n^3)` running time algorithm. A better solution is to iterate over the array, keeping track of the sum of elements so far. At each element `a[i]`, check to see if `sum_so_far - s` is already in ...
Abstract: Sparse arrays can resolve significantly more scatterers or sources than sensor by utilizing the co-array - a virtual array structure consisting of pairwise differences or sums of sensor ...
