the bit string has exactly two 1s;
the bit string begins and ends with 0;
the bit string has the sum of its digits equal to seven;
the bit string has more 0s than 1s;
the bit string has exactly two 1s, given that the string begins with a 1.

Recall that the set {0,1}∗ is the set of all finite-length binary strings. Let f:{0,1}∗→{0,1}∗ to be f(x1x2…xk)=x2x3…xkx1. That is, f takes the first bit of a string x and moves it to the end of x, so for example a string 100becomes 001; if |x|≤1, then f(x)=x Also, suppose that g:{0,1}∗→{0,1}∗ is a function such that g(x1…xk)=0x1…xk (that is, gg puts an extra 0 in front of the given string, so for example g(100)=0100. Everywhere in this question we...

4. Consider bit strings with length l and weight k (so strings of l 0’s and 1’s, including k 1’s). We know how to count the number of these for a ﬁxed l and k. Now, we will count the number of strings for which the sum of the length and the weight is ﬁxed. For example, let’s count all the bit strings for which l + k = 11. (a) Find examples of these strings of diﬀerent lengths. What...
