Minimum Insertions / Deletions Password Update

Given a current password and a target password, return the minimum number of character insertions and deletions needed to transform the current string into the target string. Requirements Input line 1 is currPassword, the current password. Input line 2 is newPassword, the target password. Allowed operations are character insertions and deletions only. Return the minimum number of updates required to transform currPassword into newPassword. Python screenshots show a stub shaped like funcUpdation(currPassword, newPassword). Examples Input: password pss$w#rd Output: 4 Explanation: delete a and o, then insert $ and #. Notes This is an LCS-style edit-distance variant: with replacements disallowed, the minimum operation count is len(a) + len(b) - 2 * LCS(a, b). The prompt language frames this as improving weak passwords, but no password-policy validation is required.
