Write a program in java script using while loop that generate random numbers between 1 to 100 and stop looping after it generate a same number twice?

Answer 1

Note, I'm not testing this, but writing it on the fly. We'll see how it works :). Also, the formatting may be off.

while (true) {

var num = Math.round(Math.random() * 99) + 1;

if (numbers_found[num] === true) {

console.log(num, "was already found");

break;

}

numbers_found[num] = true;

console.log(num, 'added');

}

You can also change the 'console.log' to 'console.warn', 'console.error', or alert

var numbers_found = [];

while(true) {

var num = Math.round(Math.random() * 99) + 1;

if (numbers_found[num] === true) {

console.log(num, "was already found");

break;

}

numbers_found[num] = true;

console.log(num, 'added');

}
