## Minimum operation required to make N as sum of distinct powers of X

Improve Article Save Article Like Article Improve Article Save Article Like Article Given an integer N and a base X, the task is to find the minimum number of operations required to represent N as a sum of the distinct powers of X. In each operation, you can either increment or decrement N. You are allowed to make the given operation any number of timesExamples:Input: N = 7, X = 3 Output: 3Explanation: It will be optimal to increment N by 3 in 3 operations. Then, N = 10 = 30 + 33.  Input: N = 53, X = 7 Output:…

## Maximizing Subarray sum with constrained traversal and addition time

Given two integers N and M representing the Length of arr  and number of seconds. The task is to maximize the sum of the subarray where it takes 0.5secs to travel in consecutive elements and 0.5secs to add a value of the element in sum. It is given that one can start from any element.Example:Input: N = 7, M = 3, arr = { 2, 1, 3, 5, 0, 1, 4 }Output: 9Explanation:  One can start from index 1 and move to index 2 and then to index 3. Hence, the total sum is  = 1 + 3 + 5 = 9.Input: N = 6, M = 2, arr = { 1, 6, 2, 5, 3, 4…

## Sum 41 rockers ‘disbanding’ after next album and tour

## Ed Sheeran: The Sum of It All review – a surprisingly moving, intimate view of marriage, loss and mental health | Television

Cheekier viewers than me might wonder how this Disney+ documentary is going to manage to fill out an entire four-part series about the singer. Sheeran is massive, the biggest male pop star in the world, capable of selling out – as he does here – Wembley Stadium for the 12th time. Each of his albums goes to No 1; he’s played at practically every massive arena in the world. He sings with Eminem on stage; Beyoncé will perform with him. But if you only know about his life from the tabloids, or by gossip osmosis, you might…

## How Reality May Be a Sum of All Possible Realities

It’s a radical view of quantum behavior that many physicists take seriously. “I consider it completely real,” said Richard MacKenzie, a physicist at the University of Montreal.But how can an infinite number of curving paths add up to a single straight line? Feynman’s scheme, roughly speaking, is to take each path, calculate its action (the time and energy required to traverse the path), and from that get a number called an amplitude, which tells you how likely a particle is to travel that path. Then you sum up all the…
