title: how to get started with TopCoder to update/develop algorithm skills?
body: <p>at workplace, the work I do is hardly near to challenging and doing that I think I might be losing the skills to look at a completely new problem and think about different ideas to solve it. </p>
  
  <p>A friend suggested TopCoder.com to me, but looking at the overwhelming number of problems I can not decide how to get started?</p>
  
  <p>what I want is to sharpen my techniques ( not particular language or framework ). </p>
