Given a sorted (in ascending order) integer array nums
of
n
elements and a target
value, write a function to search target
in nums
. If target
exists, then return its index, otherwise return
-1
.
Example 1:
Input:nums
= [-1,0,3,5,9,12],target
= 9 Output: 4 Explanation: 9 exists innums
and its index is 4
Example 2:
Input:nums
= [-1,0,3,5,9,12],target
= 2 Output: -1 Explanation: 2 does not exist innums
so return -1
Note:
nums
are unique.n
will be in the range [1, 10000]
.nums
will be in the range [-9999,
9999]
.
