Given a binary tree with n nodes, your task is to check if it's possible to partition the tree to two trees which have the equal sum of values ...
Given a singly linked list L: L 0→L 1→…→L n-1→L n,reorder it to: L 0→L n →L 1→L n-1→L 2→L n-2→… You must do this in-place without altering the nodes ...
Given a list, rotate the list to the right by k places, where k is non-negative. For example:Given 1->2->3->4->5->NULL and k ...
1. 鏈表 數組是一種順序表,index與value之間是一種順序映射,以\(O(1)\)的復雜度訪問數據元素。但是,若要在表的中間部分插入(或刪除)某一個元素時,需要將后續的數據元素進行移動,復雜度大概為\(O(n)\)。鏈表(Linked List)是一種鏈式表,克服了上述的缺點,插入和刪除 ...
Given a singly linked list L: L0→L1→…→Ln-1→Ln,reorder it to: L0→Ln→L1→Ln-1→L2→Ln-2→… You may not modify the values in the list's nodes, only ...
