Number of Islands

Try to solve the Number of Islands problem.


Let’s consider a scenario with an (m×n)(m \times n) 2D grid containing binary numbers, where '0' represents water and '1' represents land. If any '1' cells are connected to each other horizontally or vertically (not diagonally), they form an island. Your task is to return the total number of islands in the grid.


  • 11 \leq grid.length 50\leq 50

  • 11 \leq grid[i].length 50\leq 50

  • grid[i][j] is either '0' or '1'.
