advantages ;
recursive functions can be effectively used to solve
problems where the solution is expressed in terms of
applying the same solution.
disadvantages ;
in recursive we must have an if statement somewhere to
force the func. to return without the recursive call being
executed.otherwise the funct. will never return.

the factorial of non-negative integer n is written n! and is defined as follows: n!=n*(n-1)*(n-2)........1(for values of n greater than or equal to 1 and n!=1(for n=0) Perform the following 1.write a c program that reads a non-negative integer and computes and prints its factorial. 2. write a C program that estimates the value of the mathematical constant e by using the formula: e=1+1/!+1/2!+1/3!+.... 3. write a c program the computes the value ex by using the formula ex=1+x/1!+xsquare/2!+xcube/3!+....

You have given 2 array. You need to find whether they will create the same BST or not. For example: Array1:10 5 20 15 30 Array2:10 20 15 30 5 Result: True Array1:10 5 20 15 30 Array2:10 15 20 30 5 Result: False One Approach is Pretty Clear by creating BST O(nlogn) then checking two tree for identical O(N) overall O(nlogn) ..we need there exist O(N) Time & O(1) Space also without extra space .Algorithm ?? DevoCoder guest Posted 3 months ago # #define true 1 #define false 0 int check(int a1[],int a2[],int n1,int n2) { int i; //n1 size of array a1[] and n2 size of a2[] if(n1!=n2) return false; //n1 and n2 must be same for(i=0;ia1[i+1]) && (a2[i]>a2[i+1]) ) ) return false; } return true;//assumed that each array doesn't contain duplicate elements in themshelves }
