1. 引言 The non-adjacent form (NAF) of a number is a unique signed-digit representation. Like the name suggests, non-zero values cannot be adjacent. For example: ( 0 1 1 1 ) 2 = 4 + 2 + 1 = 7 (0\ 1\ 1
首先,记 S = ∑ X i S=\sum X_i S=∑Xi,那么恰好有 S 2 \frac{S}{2} 2S条边( S S S为偶数);序列 { X i } \{X_i\} {Xi}合法的充要条件是: 对于任意 i i i,满足 X i + X i + 1 ≤ S 2 X_i+X_{i+1}\le \frac{S}{2} Xi+Xi+1≤2S 这种东西 Kidulthood 就
