题目描述

Following recent rains, water has accumulated in different spots within Farmer John's field, which is composed of an N x M grid of squares. Each square is either marked with 'W' for water or '.' for dry land. The primary objective is to determine the number of distinct ponds present in the field. A pond is defined as a cluster of interconnected water squares, where each square is adjacent to all eight surrounding squares. Given a detailed layout of the field, the task is to calculate the number of ponds present.
