text: Largest area square in an array when elements can be shuffled | Function that returns true if it is possible to make a square with side equal to l ; To store the count of elements greater than or equal to l ; Increment the count ; If the count becomes greater than or equal to l ; Function to return the maximum area of the square that can be obtained ; If square is possible with side length m ; Try to find a square with smaller side length ; Return the area ; Driver code
