Given the sequence 1, 2, 5, 10, 21, 42, 85,170,341 ...... Result of N modulo m Recursive f [I] = f [I-2] + 2 ^ (I-1 ); Method 1: Construct a matrix and calculate the recursion formula Method 2: directly push the formula and use the recursive sum to

There is a binary theorem '\ left (a + B \ right) ^ {n} = \ sum _ {r = 0} ^ {n} \ left (\ begin {matrix} n \ r \ end {matrix} \ right) A ^ {n-r} B ^ {r }'. Combination number C (a, B) = C (A-1, B) + C (A-1, B-1 ). 'N' ^ 2' Can be recursive. Then,

Note that all vertices for '1' are queued at the beginning, and then the distance of all vertices is updated through a BFS until they cannot be updated.   1 #include 2 #include 3 #include 4 using namespace std; 5 const int dx[]={0,0,-1,1},dy[]={1,-1
