URI Online Judge Solution 2143 The Return of Radar Using Python Programming Language.

Every year after the contest that takes place in Taxiland, contestants and coaches go to the famous and renowned restaurant Radar. However, the waiters (always very kind and polite) get overwhelmed due to the amount of people, and therefore, end up taking a while to serve them.

Contestants or coaches who sit at the ends are the lucky ones, because they order only once and are served right away, but the others must always order twice, because the waiters (always very kind and polite) are careless and easily forget the orders. Besides, there's a superstition going on among the contestants and coaches that if there's not an even amount of people who don't sit at the ends, none of the university's teams will win the next contest.

So your task is to determine the sum of the number of of orders of each one to know if it's worth going to Radar. But whatever the result is, remember: it's always worth going to Radar!

Input

The input consists of the integer T (1 ≤ T ≤ 100) indicating the number of test cases and then, T integers N (3 ≤ N ≤ 104) indicating the number of people. The table is rectangular and there will be at least and at most one person at one end, i.e., if an end is empty, the other must be occupied, otherwise, the two ends must be occupied, but the number of people that are not at the ends must always be even. Read input until T = 0.

Output

Print the sum of the number of orders of each person. There's no newline between the test cases.

Output Sample

Solution Using Pytho:


while True:
    T = int(input())
    if T == 0:
        break
    else:
        for i in range(T):
            N = int(input())
            if N % 2 == 0:
                print(2 * N - 2)
            else:
                print(2 * N - 1)

URI Problem 1001 Solution Extremely Basic - - URI Online Judge Solution

URI Online Judge Problem 1001 Extremely Basic Solution using C, Python Programming Language. Read 2 variables, named A and B and make the sum of these two variables, assigning its result to the variable X . Print X as shown below. Print endline after the result otherwise you will get “ Presentation Error ”. Input The input file will contain 2 integer numbers. Output Print the letter X (uppercase) with a blank space before and after the equal signal followed by the value of X, according to the following example. Obs.: don't forget the endline after all. Samples Input Samples Output 10 9 X = 19 -10 4 X = -6 15 -7 X = 8 URI 1001 Solution in Python A = int(input()) B = int(input()) X = A + B print("X =",X); URI 1001 Solution in C: #include int main() { int A,B,X; scanf ("%d %d", &A, &B); X=A+B; printf("X = %d\n",X); return 0; }

URI Online Judge Solution 1151 Easy Fibonacci

URI Online Judge Solution 1151 Easy Fibonacci using C Programming Language. he following sequence of numbers 0 1 1 2 3 5 8 13 21 ... is known as the Fibonacci Sequence. Thereafter, each number after the first 2 is equal to the sum of the previous two numbers. Write an algorithm that reads an integer N (N < 46) and that print the first N numbers of this sequence. Input The input file contains an integer number N (0 < N < 46). Output The numbers should be printed on the same line, separated by a blank space. There is no space after the last number. Thanks to Cássio F. Input Sample Output Sample 5 0 1 1 2 3 Solution using C : #include <stdio.h> int main() { int n,i,n1,n2,t; scanf("%d",&n); for(i=1; i<=n; i++) { if(i==1) { n1 = 0; printf("%d",n1); } else if(i==2) { n2 = 1; printf("%d",n2); }

URI Online Judge Solution 1149 Summing Consecutive Integers

URI Online Judge Solution 1149 Summing Consecutive Integers using C Programming Language. Write an algorithm to read a value A and a value N. Print the sum of N numbers from A (inclusive). While N is negative or ZERO, a new N (only N) must be read. All input values are in the same line. Input The input contains only integer values, can be positive or negative. Output The output contains only an integer value. Input Sample Output Sample 3 2 7 3 -1 0 -2 2 7 Solution using C : #include <stdio.h> int main() { int a,n,s=0; scanf("%d%d",&a,&n); while(n<=0) scanf("%d",&n); while(n) { s += a++; n--; } printf("%d\n",s); return 0; }
