Write an assembly function equivalent to the following C function. If X[k] > K[k+1], it swaps X[k] and X[k+1] and returns 1; otherwise, it returns 0. You may use either conditional branch or conditional execution or their combination.

{ HINT: Recall that r0 holds the return value (if a function returns a value no bigger than 32 bits). To return 0; use: MOV r0, #0 BX lr .............. To return 1; use: MOV r0, #1 BX lr }

int swap(unsigned short X[], int k)

if (X[k] > X[k+1]) {

short tmp = X[k];

X[k+1] = X[k];

X[k] = tmp;

return 1;

else {

return 0;
