How do it more fast?

#include <iostream>
using namespace std;

int main()
{
    int x, y, c;

    cin >> x >> y >> c;

    if((x + y) < c)
    {
        cout << "Impossible" << endl;
    }
    else
    {
        for(int i = 0; i <= x; i++)
        {
            for(int j = 0; j <= y; j++)
            {
                if((i + j) == c)
                {
                    cout << i << " " << j << endl;
                    return 0;
                }
            }
        }
    }
}

There are 21 steps in this sequence:

1, 2, 3, 4, 5, 6, out, 6, 7, 8, 9, 10, 11, 12, out, 12, 11, 12, 13, 14, 15

a = int(input())
b = int(input())
print (a+b)

I'm using BS + Dijkstra but I'm getting TLE, why? I optimized solution by using edges that have capacity >= 3 * 10^6, implemented BS with iterations (without "while"), but keep getting TLE.

what if k=7?
Is l=2?

Just list all of cases like x>=y>=c or y>=x>=c
and you'll understand

        for (int i = 0; i < n; i++) {

I wrote program on Python 3, but second test is wrong for me. Why? I need a hint. Maybe, you can wrote test for my program?

Idea:
1. sort length descending
2. take first that smaller SUM in row
3. reduce SUM and colored ship
4. take next
5. finally for SUM if they == 0 -> go to next row


My solution:

[n, m] = [ int(x) for x in input().split() ]
a = []
for i in range(n):
    a.append(int(input()))
b = []
for i in range(m):
    b.append(int(input()))
a.sort(reverse=True)
color = [-1 for x in range(n)]

i = 0
while i < m:
    s = b[i]
    z = 0
    while z < n:
        aa = []
        j = z
        while s > 0:
            while j < n and a[j] > s :
                j += 1
            if j >= n:
                for ee in aa:
                    s += a[ee]
                    color[ee] = -1
                aa = []
                break
            elif color[j] != -1:
                j += 1
            else:
                s = s - a[j]
                aa.append(j)
                color[j] = i
        z += 1
        if s == 0:
            break
    i += 1
for i in range(m):
    aa = []
    cnt = 0
    for j in range(n):
        if color[j] == i:
            aa.append(a[j])
            cnt += 1
    print(cnt)
    aa.sort(reverse=True)
    ab = [str(x) for x in aa]
    ss = " ".join(ab)
    print(ss)

The statement describes the precision as 10^-9, but in the second example I see "1.41421356237309" This number has 14 digits behind decimal point. I tried submitting answers with precision 9, 14 and 16. They all WA#1 even though my calculations have to be correct. Does someone know what's the correct precision?

var
    a,b,c,d,e,f,g,h : real
begin
    read(a,b,c,d);
    e := sqrt(a);
    f := sqrt(b);
    g := sqrt(c);
    h := sqrt(d);
    writeln(h:0:4);
    writeln(g:0:4);
    writeln(f:0:4);
    writeln(e:0:4);
end.
why is my answer wrong?

For those who using prime numbers! Search biggest prime number that <= max!!!
NOT first prime number that >=min !!

У меня получилось вот что
I have this:

Почему проверка считает что ответ неверен
Why it's wrong?

test 11.please give me some test.thx!
