Answer 1

const arr = [3, 8, 1, 9, 4, 10, 7, 13, 2, 6];
const size = arr.length;
const N = 4;
         
let just_greater = Number.MAX_VALUE;
let just_smaller = Number.MIN_VALUE;
 
for (let i = 0; i < size; i++) {
    if (arr[i] > N && arr[i] < just_greater) {
        just_greater = arr[i];
    }
    if (arr[i] < N && just_smaller < arr[i]) {
        just_smaller = arr[i];
    }
}
 
console.log("just_smaller: " + just_smaller);
console.log("N: " + N);
console.log("just_greater: " + just_greater);
 
 
 
 
 
/*

"just_smaller: 3"
"N: 4"
"just_greater: 6"
