Given a sorted array of integers, this function returns the index of a given target value. If the target value is not present in the array, it returns -1.
About this solution: This solution is correct and demonstrates a good understanding of time complexity.
Given a sorted array of integers and a target value, this function will return the index of the target value if found, or -1 if not found.
About this solution: The candidate's solution is complete and solves the problem. The candidate has used binary search, which is the most efficient way to search a sorted array for a target value.
This problem deals with finding a target value in a sorted array of integers. The function should return the index of the target value if it is found in the array, or -1 if it is not found.
About this solution: This solution is optimal because it is O(n) time complexity. However, it only works if the array is sorted. If the array is not sorted, this solution will not work.
This problem requires the use of a binary search algorithm to find a target value in a sorted array. If the target value is found, the index of that value is returned. If the target value is not found, -1 is returned.
About this solution: The candidate's solution is complete and solves the problem. The candidate uses a binary search, which is the most efficient way to search a sorted array.
This problem involves searching for a given value in a sorted array of integers. If the value is found, the index of the target value is returned; if not, -1 is returned.
About this solution: The candidate's solution is correct and demonstrates a level of completeness. The candidate has correctly identified the problem and has provided a solution that solves the problem. The candidate's approach is general and uses a binary search algorithm, which is the optimal solution for this problem.
