URI Online Judge Solution 1069 Diamonds and Sand

URI Online Judge Solution 1069 Diamonds and Sand using Python Programming Language.

John is working in a diamond mine, trying to extract the highest number of diamond "<>". He must exclude all sand particles found "." in this process and after a diamond can be extracted, new diamonds can be formed. If he has as an input. <... << .. >> ....> .... >>>. three diamonds are formed. The first is taken from <..> resulting. <... <> ....> .... >>>. The second diamond is then removed, leaving. <.......> .... >>>. The third diamond is then removed, leaving at the end ..... >>>. without the possibility of extracting new diamonds.

Input

Read an integer N that is the number of test cases. Then follows N lines each up to 1000 characters, including "<" ,">" and "."

Output

You must print the amount of diamonds that can be extrated in each test case.

Input Sample	Output Sample
2 <..><.<..>> <<<..<......<<<<....>	3 1

Solution using Python :

T = int(input())
while T>0:
    Str = input()
    Count = 0
    Sign = 0
    for i in Str:
        if (i == "<"):
            Sign += 1
        if (i == ">" and Sign > 0):
            Count += 1
            Sign -= 1
    print(Count)
    T-=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; }
