Hello, codeforces! I am oli30twink

==================

Today I would like to describe this probem: 1878A - How Much Does Daytona Cost? From: Codeforces Round 900 (Div. 3)

I use python to solve it.

Let's start! 1. Number of tests: we should input a nuber and this number would be used in while cycle, so our beginning would be like this:

###

2. We should break into two pieces n and k given in one line, so let's write the idea down:

###

3. Let's probably do the same with line given us to check(a), it would be like:

###

4. Now let's create some variables, we would need:

###

5. Use cycle for to compare the number k and all elements from a:

###

6. Lastly, we would make the result of their comparage and use s to exclude options, where we print YES NO:

if at == k:
    print("YES")
    s = s + 1
    break

Let's sum it all up! Our programm would look like this:

nk = str(input())

    nkn = nk.split(' ')

    n = int(nkn[0])

    k = str(nkn[1])

    a = str(input())
    b = a.split(' ')
    c = list(b)

    t = 0
    s = 0

    for i in range (n):
        at = c[t]
        t = t + 1
        if at == k:
            print("YES")
            s = s + 1
            break
    if s == 0:
        print("NO")

Thanks for your attention and good luck!!!
