I did have some idea that, for fixed index i, the value of GCD (i, j) will be decreasing as GCD (i, j) >= GCD (i, j + 1). Also, because GCD (i, j + 1) must be equal or divisor of GCD (i, j), the number of distinct value X of GCD (i, j), GCD (i, j + 1), ..., GCD (i, N) will satisfies 2^X <= A [i]. giovanni west liberty ky https://sanificazioneroma.net
