(1) The int ascii_to_integer (char *str) function is implemented.Requirement: This string argument must contain one or more numbers, and the function should convert the numbers to integers and return the integer. If the string argument contains any non-numeric characters, the function returns zero. Don't worry about arithmetic overflow.tip: Every number you find, multiply the current value by 10 and add the

In the development of PHP, because of our country's language environment problems, so we often need to deal with the Chinese. In PHP, we all know that there are special MB_SUBSTR and Mb_strlen functions that can intercept and calculate the length of Chinese, but since these functions are not the core functions of PHP, they are often not open. Of course, if you are using your own server, just open it in php.ini. If the virtual host is used, and the server does not have the function to open this a

longest Substring without repeating Characters Given a string, find the length of the longest substring without repeating characters. For example, the longest substring without repeating to letters for ' ABCABCBB ' is ' abc ', which the length is 3. For ' bbbbb ' the longest substring is ' B ', with the length of 1.
