C ++ copies the content in a vector to the end of another vector and ends with the vector.
When using the vector container, We need to copy the content of a vector to the end of another vector. How can this problem be achieved?

1. Stack-based applicationsThe Bracket matching algorithm is a typical application of the stack, so the borrowing stack is implemented to save the corresponding information;Algorithm thought: encounter the first character, judge the stack empty, character into the stack, followed by the character and the top of the stack to compare, bracket matching words, then the stack top element out of the stack, other

Title Description:
to give you a sequence of parentheses of length n, consisting of ' (' and ') ', can you find the longest valid parenthesis subsequence in this sequence? The meaning of the legal parenthesis sequence is that in this sequence, all the opening parentheses have a unique right parenthesis match; All the closing parentheses have a unique left parenthesis match. For example: (()) () () () is a sequence of valid parentheses with a length of 10, and (())) (then not.) What

Push the other half bracket, if it is a closing parenthesis and not the required parentheses,Just print the mismatch, if the right parenthesis is needed, pop out the left parenthesis. Finally see if the top of the Mystack is 0, and 0 is the print bracket
