A set is a collection of objects, denoted by $S = {a_1, a_2, ..., a_n}$, where $a_i$ are the elements of $S$.
Proof techniques are used to establish the validity of mathematical statements. In computer science, proof techniques are used to verify the correctness of algorithms, data structures, and software systems. A set is a collection of objects, denoted by $S = {a_1, a_2,
A graph is a pair $G = (V, E)$, where $V$ is a set of nodes and $E$ is a set of edges. denoted by $S = {a_1
