Consider the problem of determining whether a single-tape Turing machine ever writes

a blank symbol over a nonblank symbol during the course of its computation many

input string. Formulate this problem as a language and show that it is undecidable.

2. Show that A is decidable iff A = m 0

3. Let J = {w| either w = 0x for some x ? A tw. or w = 1y for some y ? ATM} Show

that neither J nor J¯ is Turing-recognizable.

4. Give an example of an undecidable language B, where B =m B¯
