Problem 18. predictquadrant.js

 /*Question

Predict the quadrant
Given a point on a two dimensional plane, predict the quadrant to which it belongs.
Quadrants are named as Q1, Q2, Q3 and Q4. Given a point P(x, y), quadrant of P is defined as
follows.

Q1, if x > 0 and y > 0
Q2, if x < 0 and y > 0
Q3, if x < 0 and y < 0
Q4, if x > 0 and y < 0
Input
First line contains a positive integer n, denoting the number of test cases. It is followed by
n lines.
Each of the n lines contains two space separated integers x and y. Assume that neither x nor y
is 0.

Output
n lines containing the quadrant to which the corresponding point belongs.

Example
Input:

2
2 -9
1 3
Output:

Q4
Q1
First line is 2, which means there are 2 test cases. Next 2 lines will contain one point each.

First point is (2, -9). It belongs to fourth quadrant, so we should print Q4.

Second point is (1, 3). It belongs to first quadrant, so we should print Q1.

Problem 16. chocolatebills.js

  /*Question Chocolate bill Bablu went to a shop to buy some chocolates and ice creams. Help him to calculate the bill. Input 4 lines containing one integer each First line denotes the cost of 1 chocolate. Second line denotes the number of chocolate bought by Bablu. Third line denotes the cost of 1 ice cream. Fourth line denotes the number of ice creams bought by Bablu. Output One line containing one integer, denoting the total money to be paid by Bablu. Example Input: 5 3 15 2 Output: 45 Explanation: First line contains 5, which means the cost of one chocolate is 5 rupees. Second line contains 3, which means Bablu bought 3 chocolates. Third line contains 15, which means the cost of one ice cream is 15 rupees. Fourth line contains 2, which means Bablu bought 2 ice creams. So, the total bill is 45 rupees. */ let fs = require ( "fs" ); let data = fs . readFileSync ( 0 , 'utf-8' ); let idx = 0 ; data = data. split ( ' \n ' ); function readLine () { i...
