The algorithm is designed and the code is written out to remove the repeated characters in the string, and no additional cache space is used.Note: The ability to use an additional one or two variables, but does not agree to open an additional array copy.Simple question directly on the code:#include Keep it up those write several algorithms per week, entertainment!

= [=] (touch * touch, event * event) { // Do something }; Dispatcher-> addeventlistenerwithscenegraphpriority (mylistener, mysprite1 ); Dispatcher-> addeventlistenerwithscenegraphpriority (mylistener, mysprite2 ); The principle is to check the listener list in Dispatcher, for example, mylistener or other added listener. Then, each listener checks the items in the listener to see if the conditions can be met, for example, mysprite1 and mysprite2. Then perform the corresponding operation.

, but the pin variable can refer to the memory unit after the array. 4, pay attention to the operation of the pointer variable.So, with an array of famous arguments, when the function is called, the first address of the data is actually passed to the formal parameter (note that the value of the array is not passed to the parameter).Note that after the function is called, the element value of the real parameter group may change, and the change in this value is not actually passed from the formal
