样例
Input #1
998244353
Output #1
143
We have $998244353 = 119 \times 2^{23} + 1$, in other words, the triple $(a, b, c) = (119, 23, 1)$ satisfies $N = a \times 2^{b} + c$.
The value $a+b+c$ for this triple is $143$.
There is no such triple where $a+b+c \leq 142$, so $143$ is the correct output.
Input #2
1000000007
Output #2
49483
We have $1000000007 = 30517 \times 2^{15} + 18951$, in other words, the triple $(a, b, c) = (30517, 15, 18951)$ satisfies $N = a \times 2^{b} + c$.
The value $a+b+c$ for this triple is $49483$.
There is no such triple where $a+b+c \leq 49482$, so $49483$ is the correct output.
Input #3
1
Output #3
1
Note that we have $2^0 = 1$.
Input #4
998984374864432412
Output #4
2003450165
