Consecutive Cell Groupings

Given a grid, where each cell contains a number representing an ID, write a function to count how many distinct groups of connected cells (cells with the same ID) exist. Cells are considered connected if they are adjacent either horizontally or vertically. Input Format: - The first line contains two integers, m and n, the dimensions of the grid. - The next m lines contain n integers (representing IDs). Output Format: - Output the total count of distinct groups. Example: Input: 4 4 1 1 0 0 0 2 2 0 1 1 0 0 0 0 0 3 Output: 4
