c-updating a DictionaryTime limit:1000MS Memory Limit:131072KB 64bit IO Format:%lld %ll U Submit Status Practice CSU 1113DescriptionIn this problem, a dictionary is collection of key-value pairs, where keys be lower-case letters, and values are non -negative integers. Given an old dictionary and a new dictionary, find out what were changed.Each dictionary is formatting as follows:{key:value,key:value,..., key:value}Each key was a string of lower-ca
1 + 2 + 3 = 6 cubes, and so on. Thus, the I-th level of the pyramid must has 1 + 2 + ... + (i -1) + i cubes. Vanya wants to know, the maximum height of the pyramid, the he can make using the given cubes.InputThe first line contains an integer n (1≤ n ≤104)-the number of cubes given to Vanya. OutputPrint the maximum possible height of the pyramid in theSample InputInput1Output1Input25Output4HintIllustration to the second sample:

The trie tree can generally be used to find the closest to the specified value, and the binary trie tree can also find the value that is farthest from the specified value, that is, an XOR or maximum value, because each node has up to two child nodes.

(1) Question: Given an array, find two numbers in the array so that the difference or value of these two numbers is the largest
(2) point: For each element in the array, the binary trie tree looks for an XOR or maximum value. It should
Preface: This set of questions can not be found anywhere, the CSU can not submit the above. Finally in Hunan Normal University OJ found, but this normal university OJ is not good to use, each submission must be login again do not say, still do not support LLD, I also waste a lot of time to change WA.
Thought: The data quantity is small, direct brute force solves can.

Note that in many embedded environments, the export command is not provided and environment variables are not recorded. Is there no way at this time? Maybe the only way is to add the environment variable to the application
