Problem 31. pattern3.js (*** Revise***)

 /*Question

Given a positive integer n, generate the following format.
suppose n is 3, then the format is

1
1 2
1 2 3


Input: One line containing a positive integer, denoting n .
Output: Above described format.

Example:
Input:
5

output:
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5

Algorithm:
1) Read the input number
2) Print the pattern

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...
