Greedy algorithms are a class of algorithms used in computer science to solve optimization problems. These algorithms work by making the locally optimal choice at each step with the hope of finding a global optimum solution. In other words, at each step, they choose the option that looks best at the moment, without considering the…
In computer programming, modular exponentiation, or modpow for short, is a common operation used in cryptography and other mathematical applications. It involves calculating the remainder of a number raised to a power modulo another number, where the modulo operation returns the remainder of the division of the first number by the second number. This article…
Given an integer n, return an array ans of length n + 1 such that for each i (0 <= i <= n), ans[i] is the number of 1‘s in the binary representation of i. Example 1: Input: n = 2 Output: [0,1,1] Explanation: 0 –> 0 1 –> 1 2 –> 10 Example 2: Input: n = 5 Output: [0,1,1,2,1,2] Explanation: 0 –> 0 1 –> 1 2…
