In my case, I ask to shoot when I pass the same position, the first and second case everything works fine but in the next, supposedly shot but nothing happens.
EDIT:
When i add if-else statement part of the problem is solved. But i don’t understanding why?

#43

I don’t understand the fact that we have to hit once a round which is 8 passes while we cannot possibly choose our mountain at a specific basis.

#44

Because it’s the game’s rule?

#48

For two days I can’t solve it.I don’t understand. Why it doesn’t fire when MH:9 i:3 SX:3? Help, please.

EDIT MOD: Nope. Read above, and the FAQ, don’t post your full code, explain your problem etc

#49

I’m sorry. I stocked each MH in an array.

if(MH[i]!=0 & SX==i)

I wrote debugg massage. It must shoot when MH=9 i=3 SX=3 but it don’t. And I don’t understand why.

#50

You need to print a action ( FIRE or HOLD) only once per turn (while-loop)

Are the MHs entered after each pass?

#52

Yes, they are.

#53

I don’t know. Is it a mistake in task? This morning, when I was solving it spaceX and spaceY variables were the SX and SY and the task worked normally. A man, who changed it, look at the horizontal coordinate of ship with debugging massage. It’s 0, 1, 2, 3, 4, 5, 6, 7, 7 (ship avove mountain 7 and directed to the right) then 6, 5, 4, 3, 2, 1, 0, 0, 1 (still above mountain 0).
P.S. Sorry for my poor english.
P.P.S. I liked it more when it was SX, SY, MH. It’s more easy and concisely IMHO :slight_smile:

I do not understand how to access the heights of individual mountains. Insight would be welcome.

#55

The for-loop will give you each mountain heights (MH)

#56

Thank you! Solved!

#57

I understand this, but I cannot figure out how to find the height of a specific mountain.

#58

It’s in the ordered input.

#59

With this code doesn’t working, I don’t know why… It gives FIRE but doesn’t make it.
            if(mountainH != 0 && mountainH == spaceY - 1 && i == spaceX)
                printf(“FIRE\n”);

#60

Two mountains with equal heights… should be fired before you are just above one of them.

#61

Hello there :slight_smile: I have a problem with doing this exercise.I have in for loop if and if else statement which resolve which mountain is the highest.its looking like this

(for loop)
if mh[i] == 9
h = i
else if mh == 8
h = i
…and so on.and, outside for loop, there is logic for moving my ship ( if spacex > h then hold) and so, but i dont know why, when i have mountain with 9 height and mountain with 6 height which is further, the spaceship just go after the highest mountain to destroy this smaller mountain, and of course it crashes on return.Any help?

#62

why not store the highest value like this

max = 0
for loop
  if mh[i] < max
    max = mh[i]

what if your ship is on the wrong side and spacex < h (ex: spacex = 2 and h = 5), it won’t work, the logical operator you’re looking for is != which means ‘different than’ and is the opposite of == which means ‘equals to’

#63

I officially give up. I’m doing this in Javascript and I cannot figure it out. Moreover, the modulo doesn’t appear to work and variable values are out of whack. For example,

printErr(spaceY);
    if (spaceY === 10) {
        print(“FIRE”);
    } else {
        print(“HOLD”);
    };

That correctly prints out the value for spaceY as 10, 9, 8 etc. But it will always fire, regardless of the value of spaceY. And if I set it the if statement to only fire if spaceY equals anything but 10, it will NEVER fire.

#64

SpaceY is useless as f**k for this puzzle anyway. :smiley:

You need to find the hightest moutains then fire when you’re above
