How I can return the count values using the int datatype //
for base case when we hit return 1 and return 1+ recursive call
Recursion codepad problems
@Vikaspal, i think the code you shared is incorrect ,
coming to your question there are many ways in which you can count the number of combination
- take a global variable and increment it whenever you will hit the base case
- take a count variable as reference you can increment it the same way as only one function stack works at a time on the count variable
- you can store the combination of strings in a vector, and print vector.size()
