Sum of all sub arrays in O(n) Time
Given an array write C# program to find the sum of all the possible sub-arrays. For.e.g. int [] a = {4, 2, 1}; Output: Possible subarrays – {4}, {2}, {1}, {4, 2}, {2, 1}, {4, 2, 1} So, sum = 4+ 2+ 1 + 6 + 3 + 7 = 23 Solution Brute force approach Problem with below program is iterating over all pairs of … Continue reading Sum of all sub arrays in O(n) Time

Primitive Root
Question: Given a prime number n and mod k number find out whether provided prime number n is having a primitive root mod k Answer A primitive root mod n is an integer g such that every integer relatively prime to n is congruent to a power of g mod n. That is, the integer g is a primitive root (mod n) if for every number a relatively prime to n there is an integer z such that a = (gz (mod n)) for example: 2 is a primitive root mod 5, because for … Continue reading Primitive Root
