count_odd_numbers_below_n.js

// Description:
// Given a number n, return the number of positive odd numbers below n, EASY!

// Examples (Input -> Output)
// 7  -> 3 (because odd numbers below 7 are [1, 3, 5])
// 15 -> 7 (because odd numbers below 15 are [1, 3, 5, 7, 9, 11, 13])
// Expect large Inputs!

// SOLUTION:

function oddCount(n) {
    return Math.floor(n / 2);
}
