Here's another method. Let's assume the maximum digit of number x is p.For example, the maximum digit of 260d7 is d(13).
If the binary form of number x contains 2^p ,then x will get a decrease after those steps.Otherwise,it not.
Now you see that only p matters the result.We can enumerate the p and form a dp[i][0/1][0/1], which means IN THE FIRST i DIGITS,whether x<L or x=L and whether the p has appeared in x.We can enumerate the next digit to transfer it.If the current digit we enumerate contains 2^p,we just simply discuss about it.
Time Complexity:O(T*16*16*2*2*16)
