Steps to get out of complete binary tree



You are given two integers A and B. A describes the number of nodes in complete binary tree.
You are B steps away from your destination in the worst case.

Initially, you can be at:

The root node of the tree and can only move bottom of the tree.

Any leaf node of the tree and can only move up the tree.

Find and return an array of integers C of size 2
where

C[0]: The number of nodes which are at B steps from the root, i.e. the number of nodes such that,
starting at that root, you have to take
B steps downwards to reach the node.

C[1]: The number of nodes such that the maximum distance from the node to any leaf in the subtree of the node is B.

N number of balloons are kept at different heights. You are asked to find out number of arrows to burst them. When an arrow hits the balloon it goes one level down.
Assume that the balloons are having same size.

for example given the balloons heights as array(Array will be given in decreasing order of size) :
5 4 3 3 2 2 1 1 1
minimum number of arrows to shoot them is: 3

explanation:
using first arrow shoot: 5 4 3 2 1
using second arrow shoot: 3 2 1
using third arrow shoot: 1

Example 2:
5 4 2 1

minimum number of arrows to shoot them is: 2
using first arrow shoot: 5 4
using second arrow shoot: 2 1

Expecting the solution to be in O(1) space complexity.

In a garden, there are several apples trees planted in a grid format. Each point (i,j) in the grid has |i| + |j| apples.

Allie can buy a square plot centred at (0,0). Find the minimum perimeter of the plot (1 unit having length = 1) such that she can collect at
least X apples. All plants on the perimeter of the plot are also included.

Sample:

Input = 1 Output = 8
input = 11 Output = 8
Input = 13 Output = 16

You are required to collect N numbers from a bag. Initially, the bag is empty. Whenever you put a number X in the bag, then the owner of the bag asks the question.

The questions are as follows:

. What is the greatest integer that is smaller than X and present inside the bag?

. What is the smallest number that is greater than X and present inside the bag?

If you answer both the questions correctly, then you can put X inside the bag. Your task is to answers the questions that are asked by the owner of the bag. If no such numbers exist in the bag print -1.



Example:
5 (Number of elements in the bag)
1
4
2
3
7


output:
-1 -1
1 -1
1 4
2 4
4 -1

Given an array of integers A. calculate the sum of A[i] %A[j] for all possible i,j pair. return sum%(10^9+7) as an output solve this problem on o(n).

input :-
A=[1,2,3]
Output:-
5
Explanation:-
(1%1)+(1%2)+(1%3)+(2%1)+(2%2)+(2%3)+(3%1)+(3%2)+(3%3)

Select a random point uniformly within a rectangle, (The side of rectangle is parallel to the x/ y grid).

Follow-up: Given multiple non-overlapped rectangles on the 2D grid, uniformly select a random point from the rectangles.

Code an algorithm for a game consisting of two players. The input is a positive integer x. Each round, a player deducts a perfect square from the number. The player can choose any perfect square as long as it is less than or equal to the current number and greater than 0. The current player wins if the number becomes 0 after his deduction.

Print an unbalanced binary tree in level order with new lines after each level.

Say you have two large files (100 TB each) and only 1 MB of RAM. What's an efficient algorithm that will print the missing lines (diff)? The files don't necessarily contain duplicates.

The two files are not sorted and could have different ordering in both files.

e.g.:

File1 File2
A B
B A
C C
D E
F D
F

Output:
File 2: E
The input are two large files (containing strings).

The output is a list of strings telling you the presence of a line in File X and not in File Y.

Question 2: Optimize the problem for total project cost and total project days to minimal.
Given the cost/hour of each worker:
[ 30, 25, 40 ]

Question 1:
There is a bunch of tasks, each task has a code with different time to complete and task dependencies. There are few workers, how to allocate the task to these workers to minimize the total time taken to complete the task.
Example:
No of worker: 3
Task id, Task Time, Task dependency:
1, 2, 0
2, 4, 1
3, 7, 0
4, 12, 1

Question 2: Optimize the problem for total project cost and total project days to minimal.
Given the cost/hour of each worker:
[ 30, 25, 40 ]

You have three Arrays.
A = {2, 5, 3, 2, 8,1}
B = {7, 9, 5, 2, 4, 10, 10}
C = {6, 7, 5, 5, 3, 7}

make an array from this three arrays which elements is present in at least two array.

This question was followed by instead of three arrays. If you have a list of array then what will be the solution? Also what will be the time complexity?

Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand.

(i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2]).

You are given a target value to search. If found in the array return its index, otherwise return -1.

You may assume no duplicate exists in the array.

Your algorithm's runtime complexity must be in the order of O(log n).

you are provided a binary array, and a integer k, choose any k bits of array at a time and flip all the bits, maximize the number of '1's in array.

P0, P1, ...., Pn players in tournament. In first level, P0 plays with P1, P2 plays with P3 and so on. In level 2, Winner of P0,P1 plays with winner of P2,P3. For i,j output level in which they will face each other assuming they win all games.

Given directory change command -

cd a/b/../c/d/e/../../

Output the visit count for each directory such as -
Root - 1
a - 2
b - 1
c - 2
d - 2
e - 1

Given a nested list of integers, return the sum of all integers in the list weighted by their depth.

Each element is either an integer, or a list -- whose elements may also be integers or other lists.

Different from the question where weight is increasing from root to leaf, now the weight is defined from bottom up. i.e., the leaf level integers have weight 1, and the root level integers have the largest weight.

Example 1:

Input: [[1,1],2,[1,1]]
Output: 8
Explanation: Four 1's at depth 1, one 2 at depth 2.
Example 2:

Input: [1,[4,[6]]]
Output: 17
Explanation: One 1 at depth 3, one 4 at depth 2, and one 6 at depth 1; 13 + 42 + 6*1 = 17.

Given range of routing numbers, determine which bank it belongs to.

Ex-
I/p -(123400,123500, BOA), (12538, 12548, GCU)…

For 123450 - Output BOA
12540 - Output GCU

Hi,
My virtual machine is talking to our on-premise Hadoop cluster and we have observed connections dropped by the VM after approximately 15 minutes after being established. We have tried tweaking our cluster and the VPN, but it did not work. We have also disabled any firewall or NAT: our cluster is connected directly to the Internet. We ran a TCP packet capture on one of our routers and we do see the following:

Find whether string S is periodic.
Periodic indicates S = nP.
e.g.
S = "ababab", then n = 3, and P = "ab"
S = "xxxxxx", then n = 1, and P = "x"
S = "aabbaaabba", then n = 2, and P = "aabba"
follow up:
Given string S, find out the P (repetitive pattern) of S.
