Complete the function without using loops and conditions

#javascript #webdev #interview #codenewbie

// Complete the function
function calculate(n) {
    ...
};

calculate(48); // 52
calculate(52); // 48

The function accepts one argument.
If 48 is passed then it should return 52,
& if 52 is passed then it should return 48

Write the function body without using loops (for, while..) or conditionals(if..else, ?:, switch)

You need just to...

Solution

Solve the system of 2 linear equations:

48a + b = 52
52a + b = 48

And the solution is: a = -1, b = 100. So,

function calculate(n) {
    return -n + 100
}

Awesome 🔥👍
