We were asked a couple of DSA questions around array and string manipulation
The island problem on LeetCode involves finding the number of connected islands in a grid of 1s and 0s.
Use depth-first search (DFS) or breadth-first search (BFS) to traverse the grid and count the number of islands.
Keep track of visited cells to avoid redundant calculations.
Consider diagonal movements if specified in the problem.
Example: Given grid = [[1,1,0,0],[0,1,0,1],[1,0,0,1]], the number of islands is 3.
Use a hash set to find two elements in an array that sum up to a given value x.
Create a hash set to store elements as you iterate through the array.
For each element, check if the difference between x and the current element exists in the hash set.
If it does, return the current element and the difference as the two elements that sum up to x.
