If all elements in nums are larger than mi, then the answer is -1. Return an integer array answer where answer.length == queries.length and answer[i] is the answer to the ith query. Example 1: Input: nums = [0,1,2,3,4], queries = [[3,1],[1,3],[5,6]] Output: [3,3...
Output:The duplicate elements are 1 and 4 练习这个问题 相关帖子: 在不使用任何额外空间的情况下查找数组中出现的两个奇数元素 对于包含的输入n元素,我们可以使用散列法法解决这个问题O(n)时间。这个想法是遍历数组并保持哈希表中每个元素的频率。然后,在处理完每个数组元素后,返回频率为 2 的元素。这种方法的问...
Given the arrayarrof positive integers and the arrayquerieswherequeries[i] = [Li, Ri], for each queryicompute the XOR of elements fromLitoRi(that is,arr[Li] xor arr[Li+1] xor ... xor arr[Ri]). Return an array containing the result for the givenqueries. Example 1: Input: arr = ...
* Given the array arr of positive integers and the array queries where queries[i] = [Li, Ri], * for each query i compute the XOR of elements from Li to Ri (that is, arr[Li] xor arr[Li+1] xor ... xor arr[Ri] ). * Return an array containing the result for the given querie...
There is a pattern of 4 consecutive elements in the array A, for example: A[0] -> A[3], and so on. The first number of the sequence = it's index, the 2nd number is 1, the third = index of the fourth and the fourth = 0. And, when you xor all 4 together, you always get...
https://leetcode-cn.com/problems/maximum-xor-of-two-numbers-in-an-array/submissions/ 这道题还挺有意思的。O(N)时间找出数组中两个数异或值最大。两个值异或值最大,就说明比特位要尽量不一样。而且高位比低位重要。所以所有的数根据从高到低比特位建成一颗trie树。查找的时候对于每个数字。从高位到低位...
Find logical exclusive-OR collapse all in page Syntax C = xor(A,B) Description example C = xor(A,B) performs a logical exclusive-OR of arrays A and B and returns an array containing elements set to either logical 1 (true) or logical 0 (false). An element of the output array is se...
The first line contains a single integer nn (1≤n≤50001≤n≤5000)— the length of aa. The second line contains nn integers a1,a2,…,ana1,a2,…,an (0≤ai≤230−10≤ai≤230−1)— the elements of the array. The third line contains a single integer qq (1≤q≤1000001≤q≤10000...
The first line contains integersnandq(1 ≤ n, q ≤ 105), the number of elements in the array and the number of queries. The next line containsnintegersa1,a2,...,an(0 ≤ ai < 220), the elements of the array. ...
Suppose we have an array A[] with n positive elements. We have to create another array B, such that B[i] is XOR of all elements of A[] except A[i]. So if the A = [2, 1, 5, 9], then B = [13, 14, 10, 6] To solve this, at first we have to find...
