Let ALLITERATIVE-PAIRS be the language of odd-length strings of length at least 3 over the alphabet {a,b,/} that represent pairs of /-delimited words beginning with the same letter.
More precisely, for any string S belonging to ALLITERATIVE-PAIRS:
For example, these strings would belong to ALLITERATIVE-PAIRS:
a/abbbabb
bbab/bba
.
The middle character of S is /, and every other character of Sis in {a,b}
The first character in S is the same as the character immediately following /
.
But these strings would not belong to ALLITERATIVE-PAIRS:
a/b
bbb/abb
abbabb
aab//aba
.
b/b
aaaa/aa
/
