Logic question - You are alone on an island with these items; cigarette lighter, cell phone, 2 fuse ropes Known: - each rope is consumed by fire in 60 seconds - you can't assume constant burn rate for any portion of rope, only total time - you can't cut ropes Problem: How to measure 45 seconds
The accent of the interviewer was very hard to understand. Given an array with N - 2 elements (two missing) from 1 to N, find the two missing elements in linear time and constant memory usage.
Merge Linked list
Given an input vector X, first determine the sum of 2^(of each element), then give the shortest vector Y's length which elements' sum equals the input vector. Require some binary-related logic.
Write a function Brackets(int n) that prints all combinations of well-formed brackets. For Brackets(3) the output would be ((())) (()()) (())() ()(()) ()()()
Write a function to get maximum consecutive sum of integers from an array.
You are given an n by n array filled with '0's, and you have to set randomly X number of '1's in that array. Looping and generating x random number doesn't work as you might get the same random number (especially as X gets closer to n*n, collisions will become more likely in which case you'll loop for a very long time before filling all the '1's). All positions must have the same probability to get selected, and the array might be huge.
probability of the product coming from location A is 0.8 and from location B is 0.6. What is the probability the customers will receive the product from location A or location B SQL - tested on different join , lead , lag, pivoting in sql , sub query, group by having, where, aggregate and think about how you would find outliers)
Given a list of n numbers. All numbers except one are unique. Find the number with duplicate entry.
If you can understand how the game performs, you will find answer very quickly.
