title: Getting value of some elemnets by having their difference
body: <p>I am currently working on particular algorithm, but I face with a problem that I'm not sure what I have to do to resolve it. I appreciate if anyone helps me out.</p>
  
  <p>There are some <code>objects{O1,O2,O3,.....}</code>, each of them has a value that we don't know about its amount, we call them <code>{V1,V2,V3,....}</code> also there is another element we call it <code>w(w1,w2,w3.....)</code> which shows the difference between values, I mean <code>w1=v2-v1, w2=v3-v2,w3=v4-v3</code> and so on. I'm wondering if there is any way to get value of <code>v1,v2,v3...etc</code> without having the value of <code>V1</code>?</p>
  
  <p>Looking forward for your reply guys,
  Thanks.</p>
