WebD = \On input w, 1. Run E i. For every string s printed by E, if s = w, accept w ii. Else if s &lt; w in the desired ordering, continue iii. Else if s &gt; w, reject w" Since at most a flnite number of strings of L are smaller than w in the desired ordering, so after a flnite number of strings are printed by E, we can decide if w is in L or not. So, Web1.For each way to cut w into parts so that w=w1w2…wn: 2.Run M on wi for i=1,2,…,n. If M accepts each of these string wi, accept. 3.All cuts have been tried without success, so reject.” If there is a way to cut w into different substrings such that every substring is accepted by M, w belongs to the star of L and thus M’ accepts w.

Recall that a word w is palindrome if w = wR, where wR is the word formed by reversing the symbols in w (eg. if w = 010111, then wR = 111010). For example w = WebSep 20, 2024 · You can prove it by induction on the structure of w. The idea is to show that The equation holds for w = ϵ. If the equation holds for w ′ and c is a character, then it holds for w ′ c. Hopefully you can see how this implies it holds for any string w by analogous reasoning to induction on N.

WebNov 2, 2024 · Example 12 – L = { W x W r W, x belongs to {a, b}+ } is regular. If W = abb then W r = bba and x = aab, so combined string is abbaabbba. Now, X can be expanded to eat away W and W r, leaving one symbol either a or b. In the expanded string, if W=a then W r =a and if W=b then W r =b. In above example, W r =a. x=bbaabbb.
