Allowed languages
Assembly

Write a program to find the largest number in a list of signed 8-bit integers.

Since you think this is too easy a task for your programming prowess, you've decided to make life more interesting... by computing this simple maximum in assembly. To top things off, you want to show off by also finding the minimum number in the list.

Input Specification

The first line of input will contain the integer .
The second line of input will contain space-separated signed 8-bit integers, representing the list.

Output Specification

The minimum number in the list followed by the maximum, and separated by a space.

Sample Input

5
2 3 9 0 18

Sample Output

0 18

Note

To use libc in NASM, the first line of your program should be ; libc. For all others, it should be ; features: libc.

Language Constraints

Because Assembly (ARM) runs under qemu, it is allocated 0.5s and 4096kb of RAM.

If my calculations are correct, does:

signed 8-bit integers

mean that each integer can range from -128 to 127 (inclusive)?

Yes. 8 bits means there are 8 binary digits, but since the first bit is used for the sign, the range is -2 to 2 - 1.

Hint

For those getting CE, make sure you are using the right assembler and syntax. GAS by default uses AT&T syntax, not Intel syntax. Put this at the start of your submission to use intel syntax.

.intel_syntax noprefix

Such false rumours. GAS supports Intel® syntax perfectly fine. To use that is left as an exercise for the reader.

By the way, your history "edit history") leaves a lot to be desired.

Was going to ask that when I realized my mistake, unfortunately I can't delete comments, so I improvised a comment to avoid the downvotes. Might consider adding that feature to support comment self-cleanup.

Whoops

How many of you did this one before realising they were asking for it in assembly?

Now that you've solved the problem, go solve it in assembly!

???

Please make it clear whether these are signed or unsigned. I'll assume unsigned for now.

They are signed, and I've updated the statement to reflect this.
