3898. Find the Degree of Each Vertex

You are given a 2D integer array matrix of size n x n representing the adjacency matrix of an undirected graph with n vertices labeled from 0 to n - 1. - matrix[i][j] = 1 indicates that there is an edge between vertices i and j. - matrix[i][j] = 0 indicates that there is no edge between vertices i and j. The degree of a vertex is the number of edges connected to it. Return an integer array ans
