Implement a sort function using a vector. * Ask the user to enter numbers to be sorted. Add them to the vector. The user will signal the end of input by giving you a negative number. Because this is a vector, you don’t need to pass the number of entries in the vector. Then, print out the vector in order. An example run of the program is shown below:

Coding in Python, we have the function to perform this task, V col_Hdeg whichinputs the adjacency matrix A of the graph and initializes the array vert_color s tohold vertex colors. It then calculates the degree of each vertex and stores it in thearray degrees.The while loop iterates until all vertices are colored and at each iteration, thevertex v with the highest degree is colored. The array temp is used to find the currentcolors of the neighbors of vertex v and an unused smallest color is determined aftersorting this array.
