Shortest Bridge
Try to solve the Shortest Bridge problem.
We'll cover the following
Statement
We are given an binary matrix grid containing 0
s and 1
s. Each cell in the grid represents either land or water. A cell with a value of 1
represents land. Whereas, a cell with a value of 0
represents water. A group of adjacent cells with the value 1
constitutes an island. Two cells are considered adjacent if one of them is above, below, to the left of, or to the right of the second cell. We have to return the smallest number of 0
s we must flip to connect the two islands.
Note: We may assume all four edges of the grid are surrounded by water.
Constraints:
-
n
-
grid.length
grid[i].length
, such thati
-
grid[i][j]
is either or , wherei

-
There are exactly two islands in the grid.
