将数列按有序化(递增或递减)排列，查找过程中采用跳跃式方式查找，即先以有序数列的中点位置为比较对象，如果要找的元素值小于该中点元素，则将待查序列缩小为左半部分，否则为右半部分。通过一次比较，将查找区间缩小一半。-The series by ordering (increasing or decreasing) order, the process used to find the way by leaps and bounds to find that the first series of the mid-point in an orderly manner to compare the location of the object, if the elements to find the mid-point value is less than the element, will be reduced to sequences of unknown origin left part, or for the right part. Through a comparison, the half to narrow the search interval.
