Sir, how can i add the recursive function for count the number of subsequences

#1
#2

hello @chandreshmaurya

u can pass one count variable by reference in ur function.
and whenever u hit the base case increment that count variable by 1.

check this->

#3

sir, my output is coming in reverse order.

#4

sir, if i do like this … generate_subsequences(in,out,i+1,j,count); generate_subsequences(in,out,i+1,j+1,count); , Then, there is no any output. why ?

#5

…

because u have included the character at posiiton j .
and just after that u have made call on generate_subsequences(in,out,i+1,j,count);
this call will put new character at position j , so ur previous value will get discarded, that why u r not getting any output.

check now->
