Question 4 You will be given a String S which contains only two characters - A and B. Your task is to find some substring patten P in that string. The pattern P is - a substring will contain an equal number of A and B in each side. For example, in AABAABBAA, we get AB, AABB, BA, BBAA. In this problem, you have to print each pattern P present in the string S along with their frequency. Finally, print the largest pattern P. If there are multiple largest patterns, print the one that came first. Sample Input I. AABAABBAА Sample Output AB - 2 times BA - 2 times AABB - 1 times BBAA - 1 times Longest Pattern -AABB

given the strings s1 and s2, not necessarily of the same lenght, create a new string consisting of alternating characters of s1 and s2 (that is, the first character of s1 followed by the first character of s2, followed by the second characters of s1, followed by the second character of s2, and so on. Once the end of either string is reached, the reminder of the longer string is added to the end of the new string. For example, if s1 contained "abc" and s2 contained"uvqxyz", then the new string should contain "aubvcwxyz". Assign the new string to the variable s3. using python and loops

We want to create a program that reads a string and removes from it the characters between two marker characters. For example for the input text: (to buy) We need to buy (i) milk, (ii) eggs, (iii) flour, and (iv) sugar. And using "(" and ")" as the starting and ending markers, the program should output: We need to buy milk, eggs, flour, and sugar. Notice that the number of characters between the markers, and the number of markers present in the string may vary. We will assume that if a starting marker appears in the input text, its corresponding ending marker is also present in the string. Approach: The idea is to copy characters from the input text to an output string variable as long as we have not found the starting marker. From that point on, we ignore the characters in the input text until we find the ending marker. Once we find the ending marker, we resume copying characters to the output string variable, and the process repeats. Drag into the placeholders below the appropriate…

A. Which statement about regular expressions is correct? a. To find all occurrences of a matching substring for a regular expression, you must add thegflag. b. By default, pattern matching using regular expressions locates all matches in the searched string. c. To find all occurrences of a matching substring for a regular expression, you must add theiflag. d. The default behavior of a regular expression is modified by adding flags to the beginning of the expression.   B.
