Büttner tried to occupy the pupils by making them add up the integers from 1 to 100. The young Gauß surprised everybody by producing the correct answers (5050) within seconds. Can you write a computer program that can compute such sums really quickly? Given two integers Input The first line contains the number of scenarios. Each scenario consists of a line containing the numbers Output The output for every scenario begins with a line containing “ Sample Input 3 1 100 -11 10 -89173 938749341 Sample Output Scenario #1: 5050 Scenario #2: -11 Scenario #3: 440625159107385260 Source TUD Programming Contest 2006, Darmstadt, Germany |
