Problem 27. primerange.js ( find how many prime number between 5-15) When mark is outside the forloop

 /*Question

Calculate how many are prime number in the range 5-15

output:
Prime (5)
Not Prime (6)
Prime(7)
Not Prime(8)
NotPrime (9)
Not Prime (10)
Prime (11)
Not Prime (12)
Prime (13)
Not Prime (14)
Not Prime (15)
*/

// If mark variable is outside the loop, the problem

let startValue = 5;

let endValue = 15;

let mark = true;

for (let num = startValue; num <= endValue; num++) {
for (let i = 2; i < num; i++) {

if (num % i == 0) {

console.log('Not Prime');
mark = false;
break;
}
}


if (mark == true) {
console.log('Prime');
}

}

** this is completely different from the expected output because mark is outside the forloop
so it's value doesn't get refreshed for every new iteration.

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...
