I’m having a hard time understanding the question.
For eg
Why is the answer to <<<> 0.
it has a valid parenthesis at indexes 2 and 3 right??

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

@ssjgz what should be the correct output for <<><>> 4 or 2?

Neither - it should be 6:

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