Get Lowest Free - CodeChef
Problem Statement :
Chef goes to the supermarket to buy some items. Luckily there's a sale going on under which Chef gets the following offer: If Chef buys 3 items then he gets the item (out of those 3 items) having the lowest price as free. For e.g. if Chef bought 3 items with the cost 6, 2 and 4, then he would get the item with cost 2 as free. So he would only have to pay the cost of the other two items which will be 6+4=10. Chef buys 3 items having prices A, B and C respectively. What is the amount of money Chef needs to pay? Input Format The first line will contain an integer T - number of test cases. Then the test cases follow. The first and only line of each test case contains three integers A,B,C - the prices of the items bought by Chef. Output Format For each test case, output the price paid by Chef. Constraints 1≤T≤100 1≤A,B,C≤10 Sample Input 1 3 6 2 4 3 3 3 8 4 4 Sample Output 1 10 6 12

You are given Q queries. Each query consists of a single number N. You can perform any of the 2 operations N on in each move: 1: If we take 2 integers a and b where , N = a * b , then we can change N = max( a, b ) 2: Decrease the value of N by 1. Determine the minimum number of moves required to reduce the value of N to 0. Input Format The first line contains the integer Q.

View Solution →Find the Running Median
The median of a set of integers is the midpoint value of the data set for which an equal number of integers are less than and greater than the value. To find the median, you must first sort your set of integers in non-decreasing order, then: If your set contains an odd number of elements, the median is the middle element of the sorted sample. In the sorted set { 1, 2, 3 } , 2 is the median.
