for encoding that {a,b,c,...,z}<->{1,2,3,...,26} if given a list of digit e.g. [1,2,3], this may represent {1,2,3}->{a,b,c} or {12,3}->{l,c} or {1,23}->{a,w}. so there are 3 possible interpretations for list [1,2,3] so, given a list of digit, calculate the number of possible interpretations for the list.
find 3 elements in an array that sum to 0.
Implementing a dictionary of quick searching words
given two linked lists with a digit in each node, add the two linked lists together. the result must be a linked list with one digit in each node. use only one iteration of the two input lists.
What is a stack?
Pancakes, size varies, and are put in a stack with random order. You have one operation called Flip(int[] pancakes, int k) to flip all pancakes from the top one to kth pancake, write a sort(int[] pancakes]) method
1. Calculate the factorial of an array of integers. 2. How to improve the factorial algorithm?
Are two words palindrome of each other?
After Round 2 I Asked Interviewer How he would Solution for Above mentioned Q1 & Q2 questions of the Round 2 Technical Interview. Very Smartly Interviewer Did not take any effort to answer and also told me find it out by myself :)
Implement clearbit(int n, int p) function, p is the position of the bit to be cleared. Example : n is 13, p is 0. Binary representation of n : 1101. You need to clear the pth postion, means 0th position bit needs to be cleared.
