Hello @talhashamim001 in the first comparator fucntion it will be sorted in the ascending order. i.e
it will compare if the element a is less then b otherwise it will return false.
whereas in the second comparator fucntion it will compare if the first element is greater then the second then it will return true.
third comparator is wrong which you have shared.
if you have any doubt you can ask here:
Happy Learning!!
return s1>s2 in third one
third comparator will make this sorted in the lexicogrpahical fromat.
it will sort on the basis of the first letter and if the first letter is same then it will compare on the basis of the second character.
Happy Learning!!
