Algorithms Minimum steps to make binary string empty by removing alternating subsequence in each step Given a string str consisting of only '0's and '1's, the task is to make the string empty by performing minimum number of operations. An operation is defined as the removal of an alternating subsequence from str without changing the order of the remaining characters.
