implenting basic segment tree…cross checked many times…still getting wrong answer…pls help where am i doing wrong…? here is my code’s link-.http://www.codechef.com/viewsolution/2172202
Hello,
Replace this statement: float f,g,h; for this one: double f,g,h;
Meaning variables f,g and h should be double instead of float which caused losses of precision in your code. Read this StackOverFlow post.
Your logic is correct so by doing what I mentioned your code will get AC.
Some advises:
-
Next time PLEASE MAKE YOUR CODE READABLE… Don’t just name your variables a, b, c, d… It will help you code better and it will help others to help you;
-
Avoid using cin and cout (it can lead to TLE in some problems), use printf and scanf instead;
-
Indent your code, it will also make it easier to read, understand and debug.
