2. Given a boolean 2D matrix, find the number of islands.
This is an variation of the standard problem: “Counting number of connected components in a undirected graph”.

Sudoku

/*** Sudoku Given a partially filled 9×9 2D array ‘grid[9][9]‘, the goal is to assign digits (from 1 to 9) to the empty cells so that every row,   column, and subgrid of size 3×3 contains exactly one instance of the digits from 1 to 9. Backtracking Algorithm Like all other Backtracking problems, we can solve Sudoku by one by one assigning numbers to empty cells.  Before assigning a number, we check whether it is safe to assign. We basically check that the same number  is not present in current row, current column and current 3X3 subgrid. After checking for safety,  we assign the number, and recursively check whether this assignment leads to a solution or not.  If the assignment doesn’t lead to a solution, then we try next number for current empty cell.  And if none of number (1 to 9) lead to solution, we return false. ***/ #include <iostream> using namespace std; class Sudoku { public :      ...

Climbing Stairs

You are climbing a stair case. It takes  n  steps to reach to the top. Each time you can either climb 1 or 2 steps. In how many distinct ways can you climb to the top? Note:  Given  n  will be a positive integer. class Solution { public:     int climbStairs(int n) {         if (n == 0) return 0;                  if (n == 1) return 1;                  // dp space complexity is O(n)         vector<int> dp(n);         dp[0] = 1;         dp[1] = 2;                  for(int i = 2; i<n; i++)         {             dp[i] = dp[i-1] + dp[i-2];         }                  return dp[ n-1 ]...
