comment For which values of $k$, we have $A = A^{-1}$?
@ellya it is not bad etiquette but if you fully answer very simple questions it is likely that you do more harm than good to the asker.

comment Given n ranging from 1 to 100, find sum of digits equal to half of arithmetic sum of 1 to 100
rec[100][2525] is not a valid statement. If you define "int x[123]" the maximal element you can access is "x[122]".

comment is it possible to generate a unique number given a set of N integers regardless of their permutation?
Integers can be sorted in linear time and you can't really expect a sublinear algorithm anyways.

comment Given a max flow on a graph, how do you determine the actual edges that belong to the minimal cut?
@VascoMota I updated the answer to be more clear: The edges leaving the connected component (which will be only saturated edges you removed from $G$ initially) will form a min cut.
