Neither:

prefixLength: prefix:  is valid: 
1              <       false
2              <<      false
3              <<>     false
4              <<>>    true

whats wrong with my approach ?

11

but as per sample test case “<>>>” gives 2 even though its invalid ,thus “<<>><>>” also must give 6 to be answer irrespective of invalid string format. ? :confused:

12 
prefixLength: prefix:  is valid: 
1              <    false
2              <>   true
3              <>>  false
4              <>>> false
13

yes,but for string “<>>>” it is showing output as 2(refer sample test case) maybe because of “<>” part in it ,right ? ,So the tagged,string should give 6 as output na :confused: :confused:?

14

The answer to the test input:

1
<<>><>>

is 6, yes.
