Given a directed graph G $=($V$,$ E$),$ represented by an adjacency matrix A$,$ and an integer k$,$ devise a brute force algorithm that returns true if there is a vertex v whose indegree is greater than or equal to k and false otherwise. $($The indegree of vertex w is the number of vertices v such that $($v$,$ w$)$ is an edge in E$.)$ Write low$-$level pseudocode for your algorithm, explain how your algorithm works, and explain what the running time of your algorithm is$.$
