C code:
```c
while (save[i] == k) {
i += 1;
}
```

- `i` in `x22`
- `k` in `x24`
- Base address of `save` in `x25`

Compiled LEGv8 code:
```assembly
Loop:
LSL X10, X22, #3 // DW to B offset
ADD X10, X10, X25
LDUR X9, [X10, #0]
SUB X11, X9, X24
CBNZ X11, Exit
ADDI X22, X22, #1
B Loop
Exit:
```

Answer :

The given C code snippet is a while loop that iterates as long as the value of "save[i]" is equal to the value of "k". The loop increments the value of "i" by 1 with each iteration.

1. LSL X10, X22, #3: This line left shifts the value in register X22 by 3, which is equivalent to multiplying it by 8. The result is stored in register X10. This step is done to calculate the byte offset needed to access the correct element in the "save" array. ADD X10, X10, X25: This line adds the calculated byte offset (stored in X10) to the base address of the "save" array (stored in X25). The result is stored in X10. This step is done to obtain the memory address of the element in the "save" array that corresponds to the current value of "i". LDUR X9, [X10, #0]: This line loads the value at the memory address stored in X10 and stores it in register X9. This step retrieves the value of the element in the "save" array that corresponds to the current value of "i".

4. SUB X11, X9, X24: This line subtracts the value of "k" (stored in X24) from the value loaded from the "save" array (stored in X9). The result is stored in X11. This step is done to compare the value of the element in the "save" array with the value of "k". CBNZ X11, Exit: This line checks if the value in X11 (the result of the subtraction) is non-zero. If it is non-zero, it means that the element in the "save" array is not equal to "k", so the loop continues by branching back to the "Loop" label. If the value in X11 is zero, it means that the element in the "save" array is equal to "k", so the loop exits and continues execution after the loop.
