3)

Let's say that p is a pointer to memory and the next six bytes in memory (in hex) beginning at p's address are: aa bb cc dd ee ff. What value would be in x if the following code is run on a little-endian computer?

uint16_t *q = (uint16_t *)p; uint16_t x = q[1];

Input your answer as exactly 4 lower-case letters with no additional characters (so like aabb and not like 0xaabb).
