uint32_t rotate_right(uint32_t reg, uint8_t n) {
// Your code here
for(int i=0;i<n;i++){
int val = reg>>0&1;

}
int main() {
uint32_t reg;
uint8_t n;

printf("%u", rotate_right(reg, n));

}
Step 1:- iterating the for loop n times.
for(int i=0;i<n;i++) {
Step 2:- fetching the value at 0 position from reg.
int val = reg>>0&1;
Step 3:- rotate right shift once in loop
reg = reg>>1;
Step 4:- inserting the fetched value in 31 position in reg
reg = reg | val<<31;
}
Step 5:- return the reg
return reg;
