Algorithm can be defined as an interpretable, finite set of instructions for dealing with contigencies and accompanying task that has recognizable end-points for given inputs. It is a tool for solving a well computational problem. A recursive algorithm is one which calls itself.
A recursive method is a method that can invoke itself. The classical example is N factorial...
int nfact (int N) {
if (N == 2) return N else return N * nfact (N - 1);
}
The example suffers from truncation issues, because N Factorial gets very large, very quickly, with relatively small values of N, and ordinary integers do not support that. The answer, however, is sufficient for the question of "what is a recursive method?"
A recursive program/algorithm is one that calls itself again.
If you cannot find any iterative algorithm for the problem, you have to settle for a recursive one.
A recursive call in an algorithm is when a function (that implements this algorithm) calls itself. For example, Quicksort is a popular algorithm that is recursive. The recursive call is seen in the last line of the pseudocode, where the quicksort function calls itself. function quicksort('array') create empty lists 'less' and 'greater' if length('array') ≤ 1 return 'array' // an array of zero or one elements is already sorted select and remove a pivot value 'pivot' from 'array' for each 'x' in 'array' if 'x' ≤ 'pivot' then append 'x' to 'less' else append 'x' to 'greater' return concatenate(quicksort('less'), 'pivot', quicksort('greater'))
If the condition has been reached.
Step 1:- select first root node (t), start travelsing left contin
A recursive algorithm is an algorithm which calls itself with "smaller (or simpler)" input values, and which obtains the result for the current input by applying simple operations to the returned value for the smaller (or simpler) input. Heres a recursive algorithm to reverse a string char *rev(char str[],int pos1,int pos2) { if(pos1<pos2) { char temp=str[pos1]; str[pos1]=str[pos2]; str[pos2]=temp; return rev(str,pos1+1,pos2-1); } return str; } You can call this function like this char *r=rev("reverse it",0,9);

Suck a dick until it works
If the condition has been reached.
Linear search(a,item) n=length(a) for i=1 to n do if(a[i]==item) then return i end for return -1
A base case is the part of a recursive definition or algorithm which is not defined in terms of itself.

The formula, as far as I can see, is not appropriate for the algorithm.
This is not a question, this is your homework. For a start, read this: https://en.wikipedia.org/wiki/Eight_queens_puzzle
By preparing test cases we can test an algorithm. The algorithm is tested with each test case.
