hey @Karanveer in this question you are given a string of length ā€˜mā€™.
and you have to make that string of length n
such that you have two conditons which should be true at every point .
lets take the example of the sample test case only.
4 2
((
in this question you have make this string a valid string .
valid string is the sring in which the number of opening and closing bracket are equal.
in this case if you add even one more opening bracket then you woudnt be able to make this a valid string ,because in that case you need to make a string of size 6 so that it can be a valid.
that is the reason you are only left with the the option of concatenating this string with a="" in the front so that the number of opening bracker doesnā€™t increases .
and to add b with two closing brackets .
which is the only option to make it a valid string .
i hope i have cleared your doubt .
try to do the code on your own .
if you still have any doubt please write here .
Happy Learning !!
