how to find Longest Increasing Subsequence Size DPassume the indices of the array are from 0 to N - 1. So let's defineDP[i]to be the length of the LIS (Longest increasing subsequence) which is ending at element with indexi. To computeDP[i]we look at all indicesj < iand check bot...
Using Binary Search: Find a fixed point (value equal to index) in an array We can use binary search also as the array is sorted. So, if arr[pivot] is < pivot then we need to move towards the right half, else if arr[pivot] is > pivot then we need to move towards the left ...
You are given following:- - an array A consisting of N positive integers - Q queries of the form L,R,M consider all subsequences of subarray from L to R of size M. Determine the sum of Bitwise OR of all these subsequences. Bitwise OR of an empty subsequence is 0. If there is no ...

Find last subsequence in range Searches the range[first1,last1)for the last occurrence of the sequence defined by[first2,last2), and returns an iterator to its first element, orlast1if no occurrences are found. 查找在[first1,last1)中,与[first2,last2)范围内的元素最后一次匹配时出现的位置...
Given an array of integersnums, calculate the pivot index of this array. The pivot index is the index where the sum of all the numbers strictly to the left of the index is equal to the sum of all the numbers strictly to the index's right. ...
