1. 对于序列x[1,i]和y[1,j],推导递推公式 1.a 假设当前元素同样,那么就将当前最大同样数+1 2.b 假设当前元素不同。那么就把当前最大同样数“传递”下去 因此递推公式为: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 x[i]==y[j]:dp[i][j]=Max(dp[i-1][j-1],dp[i][j-1],dp[i-1]
在Python中查找数字的最小公倍数(LCM),可以使用math库中的gcd函数来计算最大公约数(GCD),然后使用以下公式计算最小公倍数(LCM): LCM(a, b) = (a * b) / G...
Hello ! I have a problem that goes : GivenNNpositive integersA1,A2,…,ANA1,A2,…,AN. FindLCM(A1,A2,…,AN)(mod1000000007)LCM(A1,A2,…,AN)(mod1000000007). Constraint :1≤N≤104,1≤N≤104,1≤Ai≤1091≤Ai≤109 My approach : ...
We have divided the gcd from the product of both numbers to get the lcm. Then in the main() function, we iterative calculate and store the gcd and lcm of all the elements of the array in gcdN and lcmN. Example Here is an example of implementing the above mentioned-steps to find ...
