Thnks Jean it works!!

However, how can i modify the code such that when 2 or more terms are repeated consecutively, it will output the the repeating term, else echo "No consecutive repeating term ?

Input:
vvvvv 20 7 7 23 0 64
uuuuu 17 0 0 24 0 146
uuuuu 17 0 0 24 0 146
uuuuu 17 0 0 24 0 146
ggggg 11 5 5 13 0 13
yyyyy 13 7 7 31 0 252
ggggg 11 5 5 13 0 13

Expected Output:
Consecutive Repeating term = uuuuu 17 0 0 24 0 146
