JavaScript Code:
function last_digit(x, y, z)
{
if ((x > 0) && y > 0 && z > 0)
{
return (x % 10 == y % 10 && y % 10 == z % 10 && x % 10 == z % 10);
}
else
return false;
}
console.log(last_digit(20, 30, 400));
console.log(last_digit(-20, 30, 400));
console.log(last_digit(20, -30, 400));
console.log(last_digit(20, 30, -400));
Sample Output:
true false false false

Returns the sum of the powers of all the numbers from start to end (both inclusive)
Example:
const sumPower = (end, power = 2, start = 1) => Array(end + 1 - start) .fill(0) .map((x, i) => (i + start) ** power) .reduce((a, b) => a + b, 0); console.log(sumPower(10)); // 385 console.log(sumPower(10, 3)); // 3025 console.log(sumPower(10, 3, 5)); // 2925
Output:
385 3025 2925
