540. Single Element in a Sorted Array 540. Single Element in a Sorted Array 题目大意: 给你一个由小到大排好序的数组,里面只有一个数出现了一次,其他数都出现了两次,要求找出那个只出现一次的数,而且时间复杂度为O(logn) 题目思路: 说实话一开始没想到,因为几乎每个数都出现了两次那么对于一个偶数i,...
Added a new function to efficiently find the single non-duplicate element in a sorted array using binary search approach. The implementation leverages the sorted nature of the array to achieve O(log n) time complexity. Test Cases Verify function returns correct element when single non-duplicate is...

Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e.,0 1 2 4 5 6 7might become4 5 6 7 0 1 2). Find the minimum element. The array may contain duplicates. 由于可能存在相同元素,所以我们不能直接使用二分搜索法,如果左端和右端都是一样的元素的话我们无法在...
You may assume no duplicate exists in the array. 题解: Binary Search, 与Find Peak Element类似. 如果nums[mid] < nums[r]说明右边一段是sorted的, minumum 只能出现在包括中点的左边一段. 反之, 说明左边一段是sorted的, minimum只能出现在不包括中点的右边一段. ...
Find an element in hidden array (人生第二道交互题) There is an array of length N consisting of non-negative integers. The array is sorted in non-decreasing order. Each number in the array appears exactly K times, except one element, which appears at least once, but less than K times....
Array element as an index This solution works only if an array has positive integers and all the elements in the array are in the range from 1 to n. Navigate the array. Update the array as for ith index :- A[abs(A[i])] = A[abs(A[i])] * -1;...
and x, find the k closest elements to x in the array. The result should also be sorted in ...
“N” and “V”: V = randi(10,[5 1]) N = randi(10,[5 1]) A = repmat(N,[1 length(V)]) [minValue,closestIndex] = min(abs(A-V’)) closestValue = N(closestIndex) Note that if there is a tie for the minimum value in each column, MATLAB chooses the first element in ...
