Minimum Swaps for Bracket Balancing | Function to calculate swaps required.
Keep track of '[.
To count number of encountered ' [ '.
To track position of next ' [ ' in pos.
To store result.
Increment count and move p to next position.
We have encountered an unbalanced part of string.
Increment sum by number of swaps required i . e . position of next ' [ ' - current position.
Reset count to 1.
