Second Step of Bracket Balancing: Pushing a Curly Brace
In the second step of the bracket balancing process, the character '{' is handled. As an opening brace, it is pushed onto the stack, which already contains an opening square bracket from the previous step. This action updates the stack's state to [ {. The operation can be summarized as 2: { ; stack: [ {, where '2' denotes the step number, '{' is the character processed, and [ { is the resulting stack.

An algorithm uses a last-in, first-out data structure to determine if a sequence of brackets is correctly matched and nested. If the algorithm begins processing the input sequence
