7kyu Binary Addition
題目:
Implement a function that adds two numbers together and returns their sum in binary. The conversion can be done before, or after the addition.
The binary number returned should be a string.
答案:
// 1
function addBinary (a, b) {
return (a + b).toString(2);
}
// 2
function addBinary (a, b) {
return ((a + b) >>> 0).toString(2);
}
// 3
const addBinary = (a, b) => (a + b).toString(2);
