Possible Triangles

/* In Geometry a triangle is real if the sum of the shortest two sides is larger than the longest side. Write a program that checks three real numbers if there is a possible triangle to be built from them. You are given lines of three real numbers. The last line will hold “End”. Print all the possibilities in the format “a+b>c”. Where a and b are the shortest sides and c is the longest.
 * The first lines hold the three real numbers, separated by single space. The last line holds the word “End”. The input lines will be distinct (no duplicates are allowed).
 * Print at the console all possible triangles found in the input sequence in format "a+b>c" (without any spaces), each at a separate line. The order of the output lines should be the same as the order they appear in the input. The numbers should be printed with 2 digits after the decimal sign. Print "No" in case no triangle is possible among the input sequence of numbers. */
