![]() ![]() Then for 2, the alphabets are a, b, c, So 3 recursive function will be called with output string as a, b, c respectively and for 3 there are 3 alphabets d, e, f.Now the recursive function will try all the alphabets, mapped to the current digit in alphabetic order, and again call the recursive function for the next digit and will pass on the current output string. Then map the number with its string of probable alphabets, i.e 2 with “abc”, 3 with “def” etc. So the idea is to form a recursive function. ![]() It can be observed that each digit can represent 3 to 4 different alphabets (apart from 0 and 1). Largest Sum Contiguous Subarray (Kadane's Algorithm)Īpproach: To solve the problem follow the below idea:.Write a program to reverse an array or string.Print Postorder traversal from given Inorder and Preorder traversals.Inorder Tree Traversal without recursion and without stack!. ![]()
