URI Online Judge Solution 1150 Exceeding Z

URI Online Judge Solution 1150 Exceeding Z using C Programming Language.
Write a program that reads two integers: X and Z (Z must be read as many times as necessary, until a number greater than X is read). Count how many integers must be summed in sequence (starting at and including X) so that the sum exceeds Z the minimum possible and writes this number.

The input may have, for example, the numbers 21 21 15 30. In this case, the number 21 is assumed for X, The numbers 21 and 15 must be ignored because they are smaller or equal to X. The number 30 is within the specification (greater than X) and is valid. So, the final result must be 2 for this test case, because the sum (21 + 22) is bigger than 30.

Input

The input contains only integer values, one per line, which may be positive or negative. The first number is the value of X. The next line will contain Z. If Z does not meet the specification of the problem, it should be read again, as many times as necessary.

Output

Print a line with an integer number representing the among of integer numbers that must be summed.

Solution using C :

#include<stdio.h>
int main()
{
    int x,z,i,s=0,j=0;
        scanf("%d",&x);
        while(1)
        {
            scanf("%d",&z);
            if(z>x)
                break;
        }
        for(i=x; ; i++)
        {
            s+=i;
            j++;
            if(s>z)
            {
                break;
            }
        }
        printf("%d\n",j);
    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...
