Should be of even length
SpletYou already found the RE R 1 = ( a ∗ b a ∗ b a ∗) ∗ such that R 1 denotes all the strings with a even number of b's (without restriction in the numbers of a's). Now you can easily find the RE for the strings with a odd number of a's. R 2 = ( … SpletIf each digit in the substring appears an even number of times, like 112233, then you know you can arrange that substring into a palindrome. If there is a digit that has an odd …
