Recurrence relations when function call is made inside loop
int fun (int n)
{
int x=1, k;
if (n==1) return x;
for (k=1; k<n; ++k)
x = x + fun(k) * fun(n – k);
return x;
}
What is the value of fun(5)?
I find it difficult to realize a recurre …

How to compute time complexity of a program if the time complexity of a function called insi... [duplicate]
This is the question-
Let $A[1,....,n]$ ba an array storing a bit $(1\,\,or\,\,0)$ at each location, and $f(m)$ is a function whose time complexity is $\theta(m)$. Consider the following program - …
