The number of times the given matrix chain multiplication expression needs to be calculated. The number of columns in the current matrix is equal to the number of rows in the next matrix. The result is an invalid error. The input is strictly legal. Even if only two characters are multiplied, the input is enclosed in parentheses. If there are at most two characters in the brackets, it is very easy. When a letter is entered directly into the stack, the

First, matrix multiplication satisfies the combination law, so we can use a rapid power method to calculate the power of the matrix.

Addition and multiplication of large numbers, addition and multiplication of large numbers When calculating the sum of two small integer numbers, it is easy to solve the problem by using the plus operator, but it will overflow for two large numbers. You cannot use the + operator. Of course, you can use the + operator. In fact, for the addition of two big integers, we use the method of addition in elementary
