Write a program that reads three edges for a triangle and computes the perimeter if the input is valid. Otherwise, display that the input is invalid. The input is valid if the sum of every pair of two edges is greater than the remaining edge.
Summary: Given integer values for red, green, and blue, subtract the gray from each value.
Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255.
Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray.
(130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray).
Given values for red, green, and blue, remove the gray part.
Ex: If the input is:
130
50
130
the output is:
80 0 80
Find the smallest value, and then subtract it from all three values, thus removing the gray.
Note: This page converts rgb values into colors.

They are exhibiting this amoeba in a national. conference. They want to know the size of the amoeba at a particular time instant. If a particular month's index is given, write a program to display the amoeba's size.

- Rock-paper-scissors is a game usually played between two people, in which each player simultaneously forms one of three shapes with an outstretched hand. These shapes are rock (a closed fist), paper (a flat hand), and scissors (a fist with the index finger and middle finger extended, forming a V). The code described above is A. both a digital and an analog code. B. an analog code. C. a digital code. D. neither a digital nor an analog code. Two user interface designers are working on the interface for a collaborative text editor. They are discussing the design of a proposed new feature: a button to irreversibly delete the current version and all past versions of a document. Designer A says, “Let's make a red button with the words ‘Delete permanently’ on it. Red means danger.” Designer B says, “No, let’s make a button with a drawing of a piece of paper going up in flames.” Which of the following best describes the designers' proposals? A.
