I am trying to make the Collatz conjecture in JS but I have a problem and I do not understand it. When I click on the button it return me 0, can someone help me please?
My js code:
let input = document.getElementById('nombre');
let btn = document.getElementById('submit');
let output = document.getElementById('output');
let coups;
let nombre = input.value;
function conjecture() {
do {
if (nombre%2 === 0) {
nombre /= 2;
output.innerHTML += nombre + '<br>';
coups ++;
} else {
nombre *= 3;
nombre ++;
output.innerHTML += nombre + '<br>';
coups++;
}
} while (nombre>1);
output.innerHtml += `La courbe a atterit en ${coups} coups.<br>`;
}
btn.addEventListener('click', conjecture);
You are reading the value before the user has had a chance to enter a number.
let nombre = input.value;
Make sure that line is inside your method which is called on click
function conjecture() {
let nombre = input.value;
... rest of your code
}
Do all n positive integer values return to integer 1 for the following system of complex equation:
5n +1 if n=odd
n/2 if n=even
Not all n positive integers return to 1, only the values represented return to 1.
For the 5+1 complex system under the odd and even conditions above, this image
