- Write a regular expression that defines strings that have an even (but nonzero) number of "a" characters followed by an odd number of "b" characters. For example, aab, aabbb, aaaab, and aaaabbb should all match the regular expression.Give regular expressions for the following L1 = set of all strings of 0 and 1 ending in 00 L2 = set of all strings of 0 and 1 beginning with 0 and ending with 1.Write a Regular Expression (RE) for: The set of strings over alphabet {0, 1} that either begin OR end (or both) with 01 Please Answer With Detailed Explanation!
- 1. write the regular expression for the following, where sigma = (a,b): i. string of length at least 2 ii. string of length at most 2 iii. all string starting with a and ending with b iv. Even length StringsCount the number of strings of length 5 over A = {a, b, c, d} that begins with a, ends with d and have exactly two b’s.(ABET 2) Construct a regular expression corresponding to the following set: {binary strings such that every odd position is a 1}. You may assume that the even positions can be a 0 or 1.
- Give a regular expression for strings that include the string: 101 as a prefix or suffix (over the letters 0–1). (or both).use java programming make a program that takes in a string. This string will be altered by switching the characters by asking two indices to switch. However, there is a twist. If the index to be switched is a vowel character, find the nearest non-vowel character and switch it instead. If the distance to the left is the same as the riht one, use the right one. Furthermore, finding the nearest non-vowel character is rotational, meaning, if you are at index '0' and the non vowel character and index '1' (right direction) is a vowel character, the new index would be the last index.Convert the following string from INFIX to PREFIX: (A+B)^(C-D^E) + (F+G)/H* +^+AB-C^DE / +FGH +AB^-C^DE / +FGH AB+CDE^- ^ FG+H/+ AB+CDE^- ^ +FGH/ (AB)+CDE^- ^ (FGH)+/
