在使用Arrays.binarySearch()的时候要注意先对数组进行排序。 Arrays.binarySearch()方法介绍: Searches the specified array of ints for the specified value using the binary search algorithm. The array must be sorted (as by the sort(int[]) method) prior to making this call. If it is not sorted,...
binary_search(a,a+10,7,排序规则)//以查找数字7为例 可以没有排序规则,也就是 binary_search(a,a+10,7)//查找数字7 但是,在查找之前,一定要注意要先排好序.也就是用一下sort. sort binary_search的排序规则应保持一致 还有就是binary_search 返回的是 个数. 没有查找到的返回零, 所以可以用来做函数...

这行的问题是当low和high的和超过2^31-1, 也就是Java里最大整数值时,整数溢出就发生了,而mid就变成负数了, 于是JVM就抓狂了,于是ArrayIndexOutOfBoundsException就发生了。 当一个数组包含多过2^30元素时,这个错误就会被发现。那么大的数组在80年代Programming Pearls第一版写就的时候难以想象,但在现在却很常...

Sort(Array, Int32, Int32) Sorts the elements in a range of elements in a one-dimensional Array using the IComparable implementation of each element of the Array. Sort(Array, Array, IComparer) Sorts a pair of one-dimensional Array objects (one contains the keys and the other contains ...

Binary searchUsually, binary search only makes sense in sorted arrays. We show that insertion sort based on repeated "binary searches" in an initially unsorted array also sorts n elements in time Θ(n 2 log n). If n is a power of two, then the expected termination point of a binary ...
