excel - Extract last number from text string -

-

i have following text in cells a1:a13. extract last number string. can see, strings contain several numbers, leading zeros, slash space, others slash, ending text others not.

i prefer formula, instead of using vba script.

 mc hope /0217 mc houston (btl-020) / 2737 mc hwy 69 s. [alltel] /5910 mc i-475 & hamilton / 0380 [ebh] mc i496 east / 0415 [on-net fiber - ebh] mc i675 / 0267 mc i-675 herzner [alltel] /0249 mc i-69 & broadway [alltel] /5404 mc i69 & dort hwy / 0309 [ebh] mc i69 & grand traverse / 0384 [ebh] mc i69 & i94 / 2472 mc i69 & i94 ii [alltel] /5847 mc i69 & m15 / 0327

should come with:

217 2737 5910 380 415 267 249 5404 309 384 2472 5847 327

edit not op

per comment: "some items have more 1 slash."

if the numbers thing can appear after number , have indeterminate number of digits in number, can use formula:

=mid(a1,find("/",a1)+1,iferror(find("[",a1,find("/",a1))-find("/",a1)-1,len(a1)))*1

enter image description here

edit: multiple forward slashes, can try 'monster' formula:

=mid(a2,find(char(1),substitute(a2,"/",char(1),len(a2)-len(substitute(a2,"/",""))))+1,iferror(find("[",a2,find(char(1),substitute(a2,"/",char(1),len(a2)-len(substitute(a2,"/","")))))-find(char(1),substitute(a2,"/",char(1),len(a2)-len(substitute(a2,"/",""))))-1,len(a2)))*1

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
