Given an integer array sorted in ascending order, write a function to search target
in nums
. If target
exists, then return its index, otherwise return -1
. However, the array size is unknown to you. You may only access the array using an ArrayReader
interface, where ArrayReader.get(k)
returns the element of the array at index k
(0-indexed).
You may assume all integers in the array are less than 10000
, and if you access the array out of bounds, ArrayReader.get
will return 2147483647
.
Example 1:
Input:array
= [-1,0,3,5,9,12],target
= 9 Output: 4 Explanation: 9 exists innums
and its index is 4
Example 2:
Input:array
= [-1,0,3,5,9,12],target
= 2 Output: -1 Explanation: 2 does not exist innums
so return -1
Note:
- You may assume that all elements in the array are unique.
- The value of each element in the array will be in the range
[-9999, 9999]
.
