LeetCode 328. Odd Even Linked List — JavaScript

最強高中生出現，真心誇張

Odd Even Linked List - LeetCode

var oddEvenList = function(head) {
    if (head === null || head.next === null) return head;
    
    let odd = head;
    let even = head.next;
    let evenhead = even;
    
    while (odd.next !== null && even.next !== null) {
        odd.next = even.next
        odd = odd.next
        
        even.next = odd.next
        even = even.next
    }
odd.next = evenhead;
    return head
};

用兩條 link list 串接奇數跟偶數，最後合併
