Constraint: Link list data node can contain only one digit. Write: Input and Output data by dry running your program. Q2. You have to find out maximum number by rearranging the digits of number. Example: 2789 Output: 9872 Complexity: O(n) Q3. Write a program for finding depth of BST (Binary Search Tree). Write by Iterative and Recursion. Q4. (a) Find output of program int mingle(int a, int b) {     int c;     c  = b /2; if (b<=2) cout< return a*2(b/2) + mingle(a,c); } int mai...
