Maximizing Unique Pairs from two arrays | Returns count of maximum pairs that can be formed from a [ ] and b [ ] under given constraints ..
Sorting the first array ..
Sorting the second array ..
To keep track of visited elements of b [ ].
For every element of a [ ] , find a pair for it and break as soon as a pair is found ..
Increasing the count if a pair is formed ..
Making the corresponding flag array element as 1 indicating the element in the second array element has been used ..
We break the loop to make sure an element of a [ ] is used only once ..
Driver code"
How can the above be solved in Python?
