Hello!  I’m Elena Granados. I’m a fullstack developer with a background in finance. 

I’m currently living in west Los Angeles.  I enjoy technology, music, nature, sustainability, and letting my mind imagine ways in which we can create a better world.  I enjoy the potential that web development has in creating unique solutions to everyday problems in an easy, convenient, an approachable way.   

There are many challenges to solve, and I want to be part of the solution, so let’s get started!

Write a function that takes an integer value and checks to see if it is even or odd using the bit-wise AND operator. 
Hint: Think about what the value of the least-significant bit will be for even and odd numbers.

function evenOrOdd(int) {
  if (int & 1) {
    console.log(`${int} is an odd number`);
  } else if (!(int & 1)) {
    console.log(`${int} is an even number`);
  }
}

What is 2^5 in binary?
100000 = 32 = [1]*2^(5)+ [0]*2^(4) + [0]*2^(3) + [0]*2^(2) + [0]*2^(1) + [0]*2^(0))

What is 2^5 - 1 in binary?
011111 = 31 = [0]*2^(5)+ [1]*2^(4) + [1]*2^(3) + [1]*2^(2) + [1]*2^(1) + [1]*2^(0))

What is the general rule for binary numbers which are of the form 2^n or 2^n - 1?
They are the One's complement fo each other, or the inverse binary digits of each other.

Even or odd -- constant O(1)
Are you here? -- polynomial O(n^2)
Doubler -- linear O(n)
Naive Search -- linear O(n)
Creating pairs -- polynomial O(n^2)
Computing fibonaccis -- linear O(n)
An Efficient Search -- logarithmic O(log n)
Random element-- constant O(1)
Is it prime? -- linear O(n)
