Can you tell the problem in my code
Subsequences problem
the error is because of the line
finda(str.substr(1));
the str length may not always be of leng 1
u`ll have to apply a check
still u dont get a correct answer for it
refer to the below code
After doing the change suggested by you in my code, can you tell why is it not working ?
i could not understand your approach
if u could elaborate on it it would help me debug it better
suppose the starting string is “abc”.
a)Call abc
b)Call on bc
c)Call on c (here string size is 1, store this string in a vector of string and return that vector)
d)The call goes to b) . Then use str[0] ie ‘b’ and add that to the vector after that vector becomes <c,bc>
Then add ‘b’ to this vector so it becomes <c,bc,b> and return that. Now control goes back to a) and so on…
there`s some issue with how u are using the vector
try making them global and adding the subsequence into the global vector
and finally sorting in the end to get reverse lexo graphic order
