title: Javascript Algorithm to find maximum size square in matrix of 1's and 0's
body: <p>You are the owner of a coworking space like WeWork and your office building is rectangular. You team just created many wall partitions to create mini offices for startups. Your office campus is represented by a 2D array of 1s (floor spaces) and 0s (walls). Each point on this array is a one foot by one foot square. Before renting to tenants, you want to reserve an office for yourself. You wish to fit the largest possible rectangular table in your office, and you will select the office that fits this table. The table sides will always be parallel to the boundaries of the office building. What is the area of the biggest table that can fit in your office?</p>
  
  <p>Functions
  biggestTable() has one parameter:</p>
  
  <p>grid: a 2D grid/array of 1s and 0s</p>
  
  <p>Input Format
  For some of our templates, we have handled parsing for you. If we do not provide you a parsing function, you will need to parse the input directly. In this problem, our input format is as follows:</p>
  
  <p>The first line is the number of rows in the 2D array
  The second line is the number of columns in the 2D array
  The rest of the input contains the data to be processed
  Here is an example of the raw input:</p>
  
  <pre><code>4
  5
  11110
  11010
  11000
  00000
  </code></pre>
  
  <p>Expected Output
  Return the area of the biggest right-angled parallelogram made of 1s in the grid. Assume the grid is surrounded by 0s (walls).</p>
  
  <p>Constraints
  Assume that the bounds of the array are the following:
  The total amount of elements in the array: width x height &lt;= 10^6</p>
  
  <p>Example</p>
  
  <pre><code>Example biggestTable() Input
  
  grid: 
      [[1, 0, 1, 1, 1],
       [1, 0, 1, 1, 1],
       [1, 1, 1, 1, 1],
       [1, 0, 0, 1, 0]]
  Example Output
  
  9
  
  
  /**
   * @param {character[][]} grid
   * @return {number}
   */
  var biggestTable = function(grid) {
      // your code here
  
      return 0;
  };
  
  let height = parseInt(readline());
  let width =  parseInt(readline());
  let grid = [];
  for (var i = 0; i &lt; height; i++) {
      grid[i] = (readline() || "").split("");
  }
  </code></pre>
  
  <p>can some one pls help with the solution.</p>
