PTA 1167 Cartesian Tree (30 分)

1167 Cartesian Tree (30 分) A Cartesian tree is a binary tree constructed from a sequence of distinct numbers. The tree is heap-ordered, and an inorder traversal returns the original sequence. For example, given the sequence { 8, 15, 3, 4, 1, 5, 12, 10, 18

1167. Minimum Cost to Connect Sticks 一直选取最小值来拼棍子

You have some number of sticks with positive integer lengths. These lengths are given as an array sticks, where sticks[i] is the length of the ith stick. You can connect any two sticks of lengths x and y into one stick by paying a cost of x + y. Yo

原题链接 考察:搜索 思路:         这道题题目描述略坑,这里简述下题意:        1.所有路线上的公交车形成等差数列,而且等差数列的最后一项再+d>60.        2.存在两个完全一样的路线.        3.求路线最少值.        由于题目提示信息:ans<=17.可以发现搜索

[LeetCode 1167] Minimum Cost to Connect Sticks

You have some sticks with positive integer lengths. You can connect any two sticks of lengths X and Y into one stick by paying a cost of X + Y.  You perform this action until there is one stick remaining. Return the minimum cost of connecting all t

ZOJ-1167-Trees on the Level

题解: 我的解法是用一个类似字典树结构的结构体来表示节点。看到另一种解法是用数组来映射二叉树的,开到14000就过了,但是我觉得是数据水了,因为题中说最多 256个节点,如果256个节点连成链型,除根节点外每个节点都是父节点的右儿子。那么数组要开pow(2, 256)个。可见这种方法是不可行的;
