This module teaches you two of the most important problem-solving techniques in the optimization domain: Greedy Techniques and Dynamic Programming. Not all problems require an exhaustive search through the solution space. Rather, consistently choosing the locally optimal solution can be proven to yield the globally optimal solution. In such situations, Greedy Techniques result in simple, highly efficient solutions. Other problems have a well-defined structure, where the same subproblem is encountered and solved multiple times. Dynamic Programming techniques allow us to compute once and reuse the solutions to recurring subproblems.

Optimization Techniques

For a given positive integer, `n`, your task is to return an array of length $n+1$ such that for each $x$ where $0 \leq x \leq n$, `result[x]` is the count of $1$s in the binary representation of $x$.

**Constraints:**

* $0 \leq n \leq 10^4$
