We have an array arr[ n-1]. We would like to 1 Compute the sum of the first i elements. 2 Modify the value of a specified element of the array arr[i] = x where 0 /5.

We have an array arr[0. We would like index of binary option geeksforgeeks 1 Compute the sum of the first i elements. A simple solution is to run a loop from 0 to i-1 and calculate the sum of the elements. The first operation takes O n time and the second operation takes O 1 time. Another simple solution is to create an extra array and store the sum of the first i-th elements at the i-th index in this new array. The sum of a given range can now be calculated in O 1 time, but the update operation takes O n time now.
This works well if there are a large number of query operations but a very few number of update operations. Could we perform both the query and update operations in O log n time? One efficient solution is to use Segment Tree that performs both operations in O Logn time. An alternative solution is Index of binary option geeksforgeeks Indexed Tree, which also achieves O Logn time complexity for both operations.
Representation Binary Indexed Tree is represented as an array. Let the array be BITree[]. Each node of the Binary Indexed Tree stores the sum of some elements of the input array.
The size of the Binary Indexed Tree is equal to the size of the input array, denoted as n. Construction We initialize all the values in BITree[] as 0. Then we call update for all the indexes, the update operation is discussed below. The parent can be obtained by removing the last set bit from the current index, i. The diagram above provides an example of how getSum index of binary option geeksforgeeks working.
Here are some important observations. The child node BITree[x] of the node BITree[y] stores the sum of the elements between y inclusive and x exclusive : arr[y,…,x. The parent can be obtained by incrementing the last set bit of the current index, index of binary option geeksforgeeks, i. The update function needs to make sure that all the BITree nodes which contain arr[i] within their ranges being updated.
We loop over such nodes in the BITree by repeatedly adding the decimal number corresponding to the last set bit of the current index. How does Binary Indexed Tree work? The idea is based on the fact that all positive integers can be represented as the sum of powers of 2. Every node of the BITree stores the sum of n elements where n is a power of 2. For example, in the first diagram above the diagram for getSumthe sum of the first 12 elements can be obtained by the sum of the last 4 elements from 9 to 12 plus the sum of 8 elements from 1 to 8.
The number of set bits in the binary representation of a number n is O Logn. Therefore, we traverse at-most O Logn nodes in both getSum and update operations. The time complexity of the construction is O nLogn as it calls update for all n elements.
Applications: The implementation of the arithmetic coding algorithm. The development of the Binary Indexed Tree was primarily motivated by its application in this case.
