inject and reduce functions behavior are the same. used with the below ruby 2.4 version only. Here is an example numbers=[1,2,3,4,5]result=numbers.inject(0,:+)puts"#{result}"result1=numbers.inject(:+)puts"#{result1}" #Sum of numbers between two numbers in Ruby For example, Two n...
Since version 2.4, Ruby has provided a concise and elegant solution for summing an array of numbers: theArray#summethod. This method simplifies the process of calculating the sum of elements in an array. The syntax for using theArray#summethod is quite straightforward: ...

Thesum()function accepts two arguments. The first argument is an iterable data structure, and the second argument is the start index. An iterable data structure could be a list of numbers, Python dictionaries, and tuples. And the start index is basically the position in the iterable data str...
You are given N numbers of the array (N ≤ 100000), all less than 108and greater than 0. Now, you are given 2 types of queries: "1 x i": Change the i-th number to x. (0 ≤ x ≤ 108) "2 Op i1 i2": Compute the sum of all two elements taken at a time within index ...
f(n) is defined as: f(n) = 1k+2k+3k+ ... +nk, so it is the sum of the k-th power of all natural numbers up to n. In this problem you are about to compute, f(1) + f(2) + f(3) + ... + f(n) Input The first line is an integerT(1 ≤T≤ 54,321), denoting...
