$1.$ The EDGECOVER problem is defined as follows: Given a simple undirected graph G $=($V$,$ E$)(|$V $|=$ n$,|$E$|=$ m$)$ and a positive integer k$,$ the task is to determine whether there exists a subset E $$ E of edges of size at most k such that every vertex in G is an endpoint of some edge in E $.$ Show that EDGECOVER in P$.[$Hint: If you can compute the maximum matching for the graph G$,$ you can use it to solve the EDGECOVER problem. A matching in a graph is a collection of edges that are pairwise disjoint. Assume that there is a polynomial$-$time algorithm to find a maximum matching.$]$
