Problem 29. pattern.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
*/

let fs = require("fs");
let data = fs.readFileSync(0, 'utf-8');
let idx = 0;
data = data.split('\n');

function readLine() {
idx++;
return data[idx - 1].trim();
}
//.......................................................................................

let num = parseInt(readLine()); // 3

for (let i = 1; i <= num; i++) // 1) i=1
{
for (let j = 1; j <= i; j++) //1) j=1 , 2<=1 false , so come out of the inner forloop
print the space and do i++ = 2
{

console.log(j); // 1) 1 now j++ is 2

}

console.log(); // this is to print space


}

TERMINAL:
Nobins-MacBook-Pro:STOC_MODULE 11SEPT 2022 nobinpunyo$ node pattern.js <input.txt 1 1 2 1 2 3

*** Without the empty console.log() , the output would look like below:-
Nobins-MacBook-Pro:STOC_MODULE 11SEPT 2022 nobinpunyo$ node pattern.js <input.txt
1
1
2

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...
