So basically here is that problem I have from school about monsters and your energy that starts at the first index and each one after it is how much energy the fight with the monster will take for you to kill it. If you win 3 battles you get the count of battles added to your energy points. So I noticed that the End of Battle string gets through the while loop even though I put it in the condition with != :/
Im sorry im a bit of a noob..
function dude(input) {
// inital energy as input(shift)
let energy = Number(input.shift());
// we create a count and ++ it for every itteration
let count = 0;
// while input[0] is NOT "End Of Battle" and energy > 0
while (input[0] !== 'End Of Battle' && energy > 0) {
// input.shift() is how much energy we will need for each monster
let monster = Number(input.shift());
// we substract that input[0].shift() energy from the starting energy
energy -= monster
count++;
if (count % 3 === 0) {
energy += count;
}
console.log(energy);
}
if(energy <= 0){
console.log(`Not enough energy! Game ends with ${count} won battles and ${energy} energy`);
}else{
console.log(`Won battles: ${count}. Energy left: ${Number(energy)}`);
}
}
dude((["200",
"54",
"14",
"28",
"13",
"End of battle"]));You are sending in a string 'End of battle' and comparing that to 'End Of Battle'. They're not the same. To protect yourself against differences like this, you can normalize strings (trim off any excess white space and convert to lower case) before comparing. I adjusted this one line and it now works:
if (input[0].trim().toLowerCase() !== 'end of battle' && ...)
function dude(input) {
// inital energy as input(shift)
let energy = Number(input.shift());
// we create a count and ++ it for every itteration
let count = 0;
// while input[0] is NOT "End Of Battle" and energy > 0
while (input[0].trim().toLowerCase() !== 'end of battle' && energy > 0) {
// input.shift() is how much energy we will need for each monster
let monster = Number(input.shift());
// we substract that input[0].shift() energy from the starting energy
energy -= monster
count++;
if (count % 3 === 0) {
energy += count;
}
console.log('energy', energy);
}
if (energy <= 0) {
console.log(`Not enough energy! Game ends with ${count} won battles and ${energy} energy`);
} else {
console.log(`Won battles: ${count}. Energy left: ${Number(energy)}`);
}
}
