intxt = input()

for i in intxt.split()[::-1]:
    print('%.4f' % int(i) ** 0.5)

Use the priority queue data structure.

input:
3 3
1 1 1
0
0 2
1 3 1 2
1 1 1 3
0
0 0
1
2 1
0 0

output:

I THINK THAT MY PROGRAM MUST HAVE AC BUT WA3
WHAT THE 3 TEST????
PLEASE POST TEST №3!!!!!!!

dic={'a':1,'d':1,'g':1,'j':1,'m':1,'p':1,'s':1,'v':1,'y':1,'.':1,' ':1,
      'b':2,'e':2,'h':2,'k':2,'n':2,'q':2,'t':2,'w':2,'z':2,',':2,
      'c':3,'f':3,'i':3,'l':3,'o':3,'r':3,'u':3,'x':3,'!':3}

m=input()
total=0
for i in range(len(m)):
    total+=dic[m[i]]
print(total)

a,b=input().split()
n=int(a)
k=len(b)
temp=n
t=k
while temp-k>0:
        n*=(temp-k)
        k+=t

print("%d"%n)

rt

i think test set is not full. my AC soulution uses floating arithmetic and does not work correctly on tests like
3
0 0 0
1 1 1
100000 100000 99999
right answer should be 2?

Input:
10 3
9 9 9

Output:
7

What is T17 ?

A nice task for implementation, but the description is quite tricky sometimes.

What if Program Counter went out of last instruction? - it is ok, you can think about it as normal termination by END command
Is NOP count towards overall operations count? - no, empty lines and only-label lines do not contribute to the overall number of executed commands
Are labels case sensitive? - no
Are operands case sensitive? - no
Are variable names case sensitive? - yes
What about int32 overflow? - guaranteed that there are no overflows
What about % operation? - the result of A % B operation is such C that 0 <= C < B and exist some integer Q: A = Q * B + C
What if 10_000_000th command is END command? - The end command terminates the program
Can variable name start from digit? - no

#include <iostream>
#include <math.h>
using namespace std;

void square()
{
    long long int n;
    scanf("%lld", &n);
    if(n!=-1)
        {
            square();
            printf("%.4f\n", sqrt(n));
        }

    return;

}
int main()
{
    square();

    return 0;
}

My program works with tests like this:

4

0 00 0

10 11

And my program give right answers but WA#1. That my code, whats wrong??

For some inputs multiple answers are possible, e.g.:

4
1011

has two possible answers: 1111 and 1001. However only 1001 seems to be accepted.

Either the wording of the problem should be changed or the alternative answers should be accepted.

Somebody can give me test case 4?
I don't understand why it's wrong answer...
