一,带函数Pred 1, all(Pred, List) ->
boolean()如果List中的每个元素作为Pred函数的参数执行,结果都返回true,那么all函数返回true,
否则返回false例子:lists:all(fun(E) -> true end,[1,2,3,4]).结果true...

Suppose a sorted array is rotated at some pivot unknown to you beforehand.
(i.e., 0 1 2 4 5 6 7 might become 4
5 6 7 0 1 2).
You are given a target value to search. If found in the array retur...

Array和List的区别在于前者可以随机访问,而后者只能顺序访问。对于把排好序的array转成BST,可以用top-down的方式,很直观也很自然,时间复杂度是O(n)。而对于List如果采用同样的方式,每次需要顺序遍历到中间节点,时间复杂度变成O(nlogn),如果换一种思路,down-top,...
