Rectangular Overlap - Amazon Top Interview Questions
Problem Statement :
You are given two lists of integers rect0 and rect1 representing coordinates (x0, y0, x1, y1) of two rectangles. (x0, y0) is the bottom left coordinate and (x1, y1) is the upper right coordinate. Return whether the two rectangles overlap. Note: if two rectangles touch only in their perimeters, they don't overlap. Example 1 Input rect0 = [0, 0, 10, 10] rect1 = [10, 10, 30, 30] Output False Example 2 Input rect0 = [0, 0, 10, 10] rect1 = [5, 5, 30, 30] Output True
Solution :
Solution in C++ :
bool solve(vector<int>& rect0, vector<int>& rect1) {
return !(rect0[3] <= rect1[1] || rect1[3] <= rect0[1] || rect0[2] <= rect1[0] ||
rect1[2] <= rect0[0]);
}
Solution in Java :
import java.util.*;
class Solution {
public boolean solve(int[] rect0, int[] rect1) {
int x1 = Math.max(rect0[0], rect1[0]);
int y1 = Math.max(rect0[1], rect1[1]);
int x2 = Math.min(rect0[2], rect1[2]);
int y2 = Math.min(rect0[3], rect1[3]);
if (x1 >= x2 || y1 >= y2)
return false;
return true;
}
}
Solution in Python :
class Solution:
def solve(self, rect0, rect1):
return not (
rect1[0] >= rect0[2]
or rect0[0] >= rect1[2]
or rect1[1] >= rect0[3]
or rect0[1] >= rect1[3]
)

Costly Intervals
Given an array, your goal is to find, for each element, the largest subarray containing it whose cost is at least k. Specifically, let A = [A1, A2, . . . , An ] be an array of length n, and let be the subarray from index l to index r. Also, Let MAX( l, r ) be the largest number in Al. . . r. Let MIN( l, r ) be the smallest number in Al . . .r . Let OR( l , r ) be the bitwise OR of the

One of the most important skills a programmer needs to learn early on is the ability to pose a problem in an abstract way. This skill is important not just for researchers but also in applied fields like software engineering and web development. You are able to solve most of a problem, except for one last subproblem, which you have posed in an abstract way as follows: Given an array consisting

Treeland is a country with n cities and n - 1 roads. There is exactly one path between any two cities. The ruler of Treeland wants to implement a self-driving bus system and asks tree-loving Alex to plan the bus routes. Alex decides that each route must contain a subset of connected cities; a subset of cities is connected if the following two conditions are true: There is a path between ever

Shashank loves trees and math. He has a rooted tree, T , consisting of N nodes uniquely labeled with integers in the inclusive range [1 , N ]. The node labeled as 1 is the root node of tree , and each node in is associated with some positive integer value (all values are initially ). Let's define Fk as the Kth Fibonacci number. Shashank wants to perform 22 types of operations over his tree, T
