Approach: 1) Initialize the result (count of islands) as 0 2) Traverse each index of the 2D matrix. 3) If the value at that index is 1, check all its 8 neighbours. If a neighbour is also equal to 1, take the union of the index and its neighbour. 4) Now define an array of size row*column to store frequencies of all sets.
WebSep 6, 2024 · We count an island based on the 1’s and one island would count as either one 1, if it surround by all 0’s (water), or one island if there is a 1 and all other 1’s surrounding it are either adjacent or above/below. We do not count diagonals. Here, we have our main algorithm that keeps track of our island count.
