Arm/maxs8

Write a function that returns the maximum value out of an array of 8-bit signed bytes.

The function has two parameters. The first parameter is the length of the array (at least 1). The second parameter is a pointer to the beginning of the array.

int max ( unsigned int length, char *array );

Sample Input

[1, 2, 3]

Sample Output

r0=3

// A test case to test your function with
.data
Array: .byte 1, 2, 3

.text
.global _start
_start:
    ldr r0, =3 
    ldr r1, =Array
    bl max
    b _start        // End of testing code

// Return maximum element of unsigned array
