Well, it is safe to turn a computer on without a RAM, but you can't really do it. RAM is one of the essential components in computers without which you can't really use a computer. You can turn it on, however, nothing will appear on your screen and the system won't boot. So, technically, it is safe, but it won't do anything to your computer as it cannot run without RAM.

Explanation:
Let's do this in Python, first we need to convert the number into string in order to break it into a list of character, then we can replace the kth character with d. Finally we join all characters together, convert it to integer then output it
def setKthDigit(n, k, d):
 n_string = str(n)
 d_char = str(d)
 n_char = [c for c in n_string]
 n_char[k] = d_char
 new_n_string = ''.join(n_char)
 return int(new_n_string)
