URI Online Judge Solution 1094 Experiments


URI Online Judge Solution 1094 Experiments using C Programming Language.
Maria has just started as graduate student in a medical school and she's needing your help to organize a laboratory experiment which she is responsible about. She wants to know, at the end of the year, how many animals were used in this laboratory and the percentage of each type of animal is used at all.
This laboratory uses in particular three types of animals: frogs, rats and rabbits. To obtain this information, it knows exactly the number of experiments that were performed, the type and quantity of each animal is used in each experiment.

Input

The first line of input contains an integer N indicating the number of test cases that follows. Each test case contains an integer Amount (1 ≤ Amount ≤ 15) which represents the amount of animal used and a character Type ('C', 'R' or 'S'), indicating the type of animal:
- C: Coelho (rabbit in portuguese)
- R: Rato (rat  in portuguese)
- S: Sapo (frog in portuguese)

Output

Print the total of animals used, the total of each type of animal and the percentual of each one in relation of the total of animals used. The percentual must be printed with 2 digits after the decimal point.
Input SampleOutput Sample
10
10 C
6 R
15 S
5 C
14 R
9 C
6 R
8 S
5 C
14 R
Total: 92 cobaias
Total de coelhos: 29
Total de ratos: 40
Total de sapos: 23
Percentual de coelhos: 31.52 %
Percentual de ratos: 43.48 %
Percentual de sapos: 25.00 %

Solution using C :

#include <stdio.h>
int main() {
    int T,sum,frog,rat,rabbits;
    sum = frog = rat = rabbits = 0;
    scanf("%d",&T);
    while(T--)
    {
        int n;
        char a;
        scanf("%d %c",&n,&a);
        sum += n;
        if(a=='C')
            rabbits += n;
        else if(a=='R')
            rat += n;
        else if(a=='S')
            frog += n;
    }
    printf("Total: %d cobaias\nTotal de coelhos: %d\nTotal de ratos: %d\nTotal de sapos: %d\n",sum,rabbits,rat,frog);
    printf("Percentual de coelhos: %.2f %%\n",((float)(rabbits)/(float)(sum))*100);
    printf("Percentual de ratos: %.2f %%\n",((float)(rat)/(float)(sum))*100);
    printf("Percentual de sapos: %.2f %%\n",((float)(frog)/(float)(sum))*100);
    return 0;
}

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 Problem 1002 Solution Area of a Circle - URI Online Judge Solution

URI Online Judge Problem 1002 Solution Area of a Circle using Python Programming Language. The formula to calculate the area of a circumference is defined as A = π . R2. Considering to this problem that π = 3.14159: Calculate the area using the formula given in the problem description. Input  The input contains a value of floating point (double precision), that is the variable R. Output  Present the message "A=" followed by the value of the variable, as in the example bellow, with four places after the decimal point. Use all double precision variables. Like all the problems, don't forget to print the end of line after the result, otherwise you will receive "Presentation Error". Input Samples Output Samples 2.00 A=12.5664 100.64 A=31819.3103 150.00 A=70685.7750 URI 1002 Solution in Python R = float(input()); R = R*R*3.14159; print("A=%.4f" % R); URI 1002 Solution in C: #include #define A 3.14159 int main() {...

URI Problem 1179 Solution Array Fill IV - URI Online Judge Solution

URI Online Judge Solution 1179 Array Fill IV  Using C, Python Programming Language. In this problem you need to read 15 numbers and must put them into two different arrays: par if the number is even or impar if this number is odd. But  the size of each of the two arrrays is only 5 positions. So every time you fill one of two arrays, you must print the entire array to be able to use it again for the next numbers that are read. At the end, all remaining numbers of each one of these two arrays must be printed beginning with the odd array. Each array can be filled how many times are necessary. Input The input contains 15 integer numbers. Output Print the output like the following example. Input Sample Output Sample 1 3 4 -4 2 3 8 2 5 -7 54 76 789 23 98 par[0] = 4 par[1] = -4 par[2] = 2 par[3] = 8 par[4] = 2 impar[0] = 1 impar[1] = 3 impar[2] = 3 impar[3] = 5 impar[4] = -7 impar[0] = 789 impar[1] = 23 par[0] = 54 par[1] = 76 par[2] = 98 Solution Using C: #include <stdi...
