Minimum Swaps brackets balancing
Detailed guide and Python implementation for the 'Minimum Swaps brackets balancing' problem.
Problem Statement
Write a function minimum_swaps_balancing(s) that takes a string s of square brackets [ and ] containing equal numbers of opening and closing brackets, and returns the minimum number of swaps of adjacent characters needed to balance the string.
- •2 <= len(s) <= 10^5
- •s contains only '[' and ']'
- •Count of '[' equals count of ']'
Examples
minimum_swaps_balancing('[]][[]')1
Swap index 2 and 3 -> '[][][]', which is balanced. (1 swap)
minimum_swaps_balancing(']]][[[')6
We can swap adjacent brackets to make it balanced, requiring 6 swaps in total.
