Kotlin Leetcode - 83. Remove Duplicates from Sorted List

題目連接

class Solution {
    fun deleteDuplicates(head: ListNode?): ListNode? {
    }
}

解題思路

這題的輸入值是 Linked List

邏輯非常的單純

迴圈比對目前的值和下一個元素的值即可

Kotlin 參考解答

class Solution {
    fun deleteDuplicates(head: ListNode?): ListNode? {
        var cur = head
        while (cur != null) {
            while (cur.next != null && cur.`val` == cur.next.`val`) { 
                cur.next = cur.next.next
            }
            cur = cur.next
        }
        
        return head
    }
}
