Binary indexed tree hackerearth
A Fenwick tree or binary indexed tree is a data structure that can efficiently update elements and calculate prefix sums in a table of numbers. This structure was Binary Indexed Tree also called Fenwick Tree provides a way to represent an array of numbers in an array, allowing prefix sums to be calculated efficiently.

Also try practice problems to test & improve your skill level. Another approach is to use the Binary Indexed Tree data structure, also with the worst time complexity O(m log n) — but Binary Indexed Trees are easier to code and require less memory space than RMQ. Notation. Before we proceed with defining the structure and stating the algorithms, we introduce some notations: Relaxing JAZZ - Soft City Night JAZZ for Evening Dinner - Chill Out Music Lounge Music 2,143 watching Live now
To compute the index for storing the strings, use a hash function that states the following: The index for a specific string will be equal to the sum of the ASCII values of the characters modulo 599. As 599 is a prime number, it will reduce the possibility of indexing different strings (collisions).

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. In the code below, we use a size of n+1 for ease of implementation. Construction To compute the index for storing the strings, use a hash function that states the following: The index for a specific string will be equal to the sum of the ASCII values of the characters modulo 599. As 599 is a prime number, it will reduce the possibility of indexing different strings (collisions). First 3 are dynamic programs. 1.triplets(advanced). You must know a data structure called "binary indexed tree" (bit), because I don't think it generally comes to anybody intuitively. It's used for getting cumulative frequency count efficiently. An array is a sequential collection of elements of same data type and stores data elements in a continuous memory location. The elements of an array are accessed by using an index.
