Here’s one I was asked during my interview:
- binary tree, nodes, each node has an ID
- root node of the tree
structure node
{
int id;
node *
left;node *
right;}
- problem: given node id 1, and node id 2, determine the
lowest common ancestor of these 2 nodes- input:
id1, id2, root- out: node
id of this ancestor nodeRead Answers(8) | 8,684 Views |

Four people need to cross a rickety rope bridge to get back to their camp at night. Unfortunately, they only have one flashlight and it only has enough light left for seventeen minutes. The bridge is too dangerous to cross without a flashlight, and it’s only strong enough to support two people at any given time. Each of the campers walks at a different speed. One can cross the bridge in 1 minute, another in 2 minutes, the third in 5 minutes, and the slow poke takes 10 minutes to cross. How do the campers make it across in 17 minutes?

Implement the following function, FindSortedArrayRotation,
which takes as its input an array of unique integers that has been sorted
in ascending order, then rotated by an unknown amount X where 0 <=
X <= (arrayLength - 1). An array rotation by amount X moves every
element array[i] to array[(i + X) % arrayLength]. FindSortedArrayRotation discovers and returns X by examining the array.
Consider performance, memory utilization and code clarity and elegance
of the solution when implementing the function.C++ Prototype
int FindSortedArrayRotation( int
array[], unsigned length ){
}
C# Prototype
static int FindSortedArrayRotation(
int[] array ){
}

A solution consists of four balls from a set of four different colors. The user
tries to guess the solution.If they guess the right color for the right
spot, record it as being in the correct ‘Location’. If it’s the right color,
but the wrong spot, record it as a correct ‘Color’. For example: if the
solution is ‘BGRR’ and the user guesses ‘RGYY’ they have 1 ‘Location’ and 1
‘Color’. A correct solution would be 4 ‘Location’ and 0 ‘Color’.Write a program to, given a solution and a
guess, calculate the response that we present to the user.Read Answers(12) | 3,597 Views |
