TCS Codevita Minimum Distance Solution

By -
Problem : Minimum Distance

Two riders A and B are travelling on a highway towards each other on two roads that intersect at right angle at speeds VAmeters/second and VB meters/second. A is at a distance of 'x' meters and B is at a distance of 'y' meters from the intersection. Calculate the minimum distance between these two riders that is possible.


                                                             Fig:Approaching Intersection
Input Format:

First line contains the distance of Rider A from intersection denoted by x
Second line contains the distance of Rider B from intersection denoted by y
Third line contains the Velocity of Rider A denoted by VA
Fourth line contains the Velocity of Rider B denoted by VB
Output Format:

Print the minimum distance between these two riders, if minimum distance is non-zero. If minimum distance is zero, print it as 0.0
Constraints:
x > 0
y > 0
VA > 0
VB > 0 
Calculation and printing of output should be done upto 11-precision

  By Parth Makadiya     I reviewed  PowerSuite set of tools in a previous post and am adding further information about their evolution through the years as part of a sponsored post series.     We’ve all heard the old saying “The only thing that stays the same is that everything changes”. And in the online marketing industry, change has always been the name of the game. From staying on top of the zoo Google keeps throwing at us, to dodging curve balls from Facebook Ads, to figuring out each new social platform that pops up – if you aren’t flexible, then online marketing may not be for you.   As our industry continuously shifts, the tools we use must change and adapt just as fast.   Through out all the changes, one tool set has continued to help SEO experts attain higher rankings, increase traffic, and spy on their competition. We know them now as  SEO PowerSuite .

We share our most cherished moments and our most painful thoughts. We divulge every aspect of our lives. We even clamor to see the  latest versions even before they're ready  for primetime.   But we sometimes forget who's watching.   We use Facebook as a tool to connect, but there are those people who use that connectivity for malicious purposes. We reveal what others can use against us. They know when we're not home and for how long we're gone. They know the answers to our security questions. People can practically steal our identities—and that's just with the visible information we purposely give away through our public Facebook profile.       The scariest part is that as we get more comfortable with advances in technology, we actually become more susceptible to hacking. A
