How to make part of text in EditText non-removable when using RedMadRobot's input-mask-android? -


i using redmadrobot's input-mask-android library set input mask edittext entering phone numbers.

public class mainactivity extends appcompatactivity {      static string input_mask_phone = "{998} [00] [000]-[00]-[00]";      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          edittext login = (edittext) findviewbyid(r.id.login);          maskedtextchangedlistener maskedtextchangedlistener = new maskedtextchangedlistener(                 input_mask_phone,                 true,                 login,                 null,                 new maskedtextchangedlistener.valuelistener() {                     @override                     public void ontextchanged(boolean b, @notnull string s) {                      }                 }         );          login.addtextchangedlistener(maskedtextchangedlistener);         login.setselection(login.length());      }  }

i setting '998', should not removed when user tries remove. '998' can removed.

<edittext     android:id="@+id/login"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:inputtype="phone"     android:text="998"/>

how make '998' not removable?

try out sample

private final string mmobileinitial ="+974 "; edittext login = (edittext) findviewbyid(r.id.login); login.settext(mmobileinitial); selection.setselection(login.gettext(), login.gettext().length());         login.addtextchangedlistener(new textwatcher() {             @override             public void ontextchanged(charsequence s, int start, int before, int count) {             }             @override             public void beforetextchanged(charsequence s, int start, int count,                                           int after) {             }             @override             public void aftertextchanged(editable s) {                 if(!s.tostring().startswith(mmobileinitial)){                     login.settext(mmobileinitial);                     selection.setselection(login.gettext(), login.gettext().length());                 }             }         });

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
