I need an NFA for the set of all strings that have an odd number of 1’s or even number of 0’s BUT NOT BOTH. please don't draw a DFA, that is very essential.

1. Write regular expressions to capture the following regular languages: (a) The set of binary strings which have a 1 in every even position. (Note: odd positions may be either 0 or 1.) (b) The set of binary strings that do not contain 011 as a substring. (c) Comments in Pascal. These are delimited by (* and *) or by { and }, and can contain anything in between; they are NOT allowed to nest, however. 2. Write a DFA...
2. a. Draw a NFA that accepts all strings over Σ = {?, ?} that either end in ?? or contain the substring ??. b. Then convert the NFA in the previous exercise to a DFA
1. Design an NFA (Not DFA) of the following languages. a) Lw E a, b) lw contain substring abbaab) b) L- [w E 10,1,2) lsum of digits in w are divisible by three) c) L-(w E {0,1,2)' |The number is divisible by three} d) The language of all strings in which every a (if there are any) is followed immediately by bb. e) The language of all strings containing both aba and bab as substrings. f L w E 0,1every...
3. [20 points] Give short answers to each of the following parts. Each answer should be at most three sentences. Be sure to define any notation that you use. (a) Explain the difference between a DFA and an NFA. (b) Give a regular expression for the language consisting of strings over the alphabet 2-(0, 1) that contains an even number of 0's and an odd number of 1's and does not contain the substring 01. (c) Give the formal definition...
All strings with an even number of a's or an odd number of b's. Question is: List the first 10 strings of the language in question #2 above in canonical order
Express as a set using set-builder notation The set of all binary strings that contain at least one 0 and at least one 1. The set of all binary strings with even length. The set of all binary strings that contain an even number of 1’s. The set of all binary strings that read the same forward and backwards
Give the DFA for each sub-problem and the product DFA for the following: {strings that have a 0 and the # of 1’s is odd}.
Write down the regular expressions for the following set of strings over {a, b}: 1.Strings that contain no more than one occurrence of the string aa. 2.All strings containing aba: 3.All strings of odd length 4.A string in this language must have at least two a's. 5.All strings that begin with a, and have an even number of b Bonus - All strings with “a” at every odd position

Regular Languages 4 4 1. Write English descriptions for the languages generated by the following regular expressions: (a) (01... 9|A|B|C|D|E|F)+(2X) (b) (ab)*(a|ble) 2. Write regular expressions for each of the following. (a) All strings of lowercase letters that begin and end in a. (b) All strings of digits that contain no leading zeros. (c) All strings of digits that represent even numbers. (d) Strings over the alphabet {a,b,c} with an even number of a's....
Draw a DFA which accepts the following language over the alphabet of {0,1}: the set of all strings such that there are no consecutive 0s, and the number of 1s is divisible by 5. Your DFA must handle all intput strings in {0,1}*. Here is a way to approach the problem: First focus only building the DFA which accepts the language: As you build your DFA, label your states with an explanation of what the state actually represents in terms...
