Reduce function hackerrank solution

Concept The reduce function applies a function of two arguments cumulatively on a list of objects in succession from left to right to reduce it to one value. Say you have a list, say [1,2,3] and you have to find reduce function hackerrank solution sum. You can also define an initial value. If it is specified, the function will assume initial value as the value given, and then reduce.

Say you have a list, say [1,2,3] and you have to find its sum. You can also define an initial value. If it is specified, the function will assume the initial value as the value given, and then reduce. It is equivalent to adding the initial value at the beginning of the list. For example:. The first line contains n, the number of rational numbers.

You are also given K lists. The i th list consists of Ni elements. You have to pick one element from each list so that the value from the equation below is maximized :. Xi denotes the element picked from the i th list. Find the maximized value Smax obtained. Note that you need to take exactly one element from each list, not necessarily the largest element. You add the squares of the chosen elements and perform the modulo operation. The maximum value that you can obtain, will be the answer to the problem. The first line contains 2 space separated integers K and M. The next K lines each contains an integer Ni , denoting the number of elements in the i th list, followed by Ni space separated integers denoting the elements in the list.

Array reduction is a common programming problem that can be found on HackerRank. In this type of problem, you are given an array of numbers and you need to find a way to reduce it down to a single number. There are a few different ways to do this, but the most common is to use a reduce function. The reduce function takes an array as its input and returns a single value. It works by iteratively applying a binary operator to the elements of the array, starting with the first two elements. The output of the binary operator is then used as the input for the next iteration, and so on. This process continues until there is only one element left in the array, which is the output of the reduce function.
