We want to check if a given string is balanced or not. At first suppose there is only one type of bracket.For this case there exists a very simple algorithm.Let depth be the current number of open brackets.Initially depth=0.We iterate over all character of the string, if the current bracket character is an opening bracket, … See more Sometimes it is required to find and output all balanced bracket sequences of a specific length n. To generate then, we can start with the lexicographically smallest sequence … See more Here we only consider the case with one valid bracket type. Given a balanced sequence, we have to find the next (in lexicographical order) balanced sequence. It should be obvious, that we have to find the rightmost … See more Given a balanced bracket sequence with n pairs of brackets.We have to find its index in the lexicographically ordered list of all balanced sequences … See more

WebOct 16, 2024 · In this HackerEarth Bracket sequences problem solution A bracket sequence is a string that contains only characters '(' and ')'. A correct bracket sequence is a bracket sequence that can be transformed into a correct arithmetic expression by inserting characters '1' and '+' between the original characters of the sequence. WebA correct bracket sequence is a bracket sequence that can be transformed into a correct arithmetic expression by inserting characters ' 1 ' and ' + ' between the original characters of the sequence. For example, bracket sequences ' () () ' and ' ( ()) ' are correct. The resulting expressions of these sequences are: ' (1)+ (1) ' and ' ( (1+1)+1) '.
