Maximize count of pairs ( i , j ) from two arrays having element from first array not exceeding that from second array | Function to return the maximum number of required pairs.
Max Heap to add values of arr2 [ ].
Sort the array arr1 [ ].
Push all arr2 [ ] into Max Heap.
Initialize the ans.
Traverse the arr1 [ ] in decreasing order.
Remove element until a required pair is found.
Return maximum number of pairs.
Driver Code.
Given arrays.
