Escape sequences allow you to send nongraphic control characters to a display device. Useful Unicode, Symbol, Unicode, Description. You can safely add this character in your html code with the entity: It is sometimes abbreviated as BS. If we talk about ASCII 7-bits there are a total of 128 characters, in which 95 are printable and 33 are not printable. We can solve this problem using two pointers without using extra space. If we see a backspace character, the next non-backspace character is skipped. Check if two strings after processing backspace character are equal or not. Traverse both the strings in reverse order. CR, 15, 13​, d, ^M, Carriage Return. Note that after backspacing an empty text, the text will continue empty. An escape sequence is a sequence of characters that does not represent itself when used inside a character or string literal, but is translated into another character or a sequence of characters that may be difficult or impossible to represent directly. Find the numbers of strings that can be formed after processing Q queries. Traverse the string S. If any char except ‘#’ is found push it at back in deque. Backspace key. 1, use echo to redirect.
