In order to qualify as a valid identifier, the string must satisfy the following conditions: It must start with either underscore(_) or any of the characters from the ranges [a, z] and [A, Z]. To execute this task we will make a regular expression using compile() that will have all the special characters which we don't want in our string. Now iterate the count arrays of both strings and difference in frequency of any character abs(count1[str1[i]-a] count2[str2[i]-a]) in both the strings is the number of character to be removed in either string. Auxiliary Space: O( 1 ). So, we can store the count of occurrences of all the characters from a Swap the last element with this element in an array and remove the last element.
