Rosetta Code: Count the coins
There are four types of common coins in [US]
- quarters (25 cents)
- dimes (10 cents)
- nickels (5 cents), and
- pennies (1 cent)
There are six ways to make change for 15 cents:
- A dime and a nickel
- A dime and 5 pennies
- 3 nickels
- 2 nickels and 5 pennies
- A nickel and 10 pennies
- 15 pennies
Implement a function to determine how many ways there are to make change for a dollar using these common coins (1 dollar = 100 cents)
My code is as below: I dont know where i made mistake, when i try in repl.it it looks okay but here it is not accepting my answer. Please help.
function countCoins() {
var count = 0;
var pennies = 1;
var nickles = 5;
var dimes = 10;
var quarteres = 25;
for(var q =0; q<=4; q++){
for(var d =0; d<=10; d++){
for(var n =0; n<=20; n++){
for(var p =0; p<=100; p++){
total = pennies * p + nickles * n + dimes * d + quarteres * q;
if (total == 100){
count++;
}
}
}
}
}
console.log(count);
return count;
}
