substring

问题 In Android is there an easy way to insert commas into a numberical value? ie if I have an EditText with 12345 in it, how can I display this as 12,345? I think I can do it using substring and chopping it up into x number of 3 number chunks then concatenating the answer with ',' between each 3 number chunk. This would be pretty easy if length of number was constant, but as the number could be from one digit to, say 20, it makes it more complex. Just curious if there is a simple and clean way to

问题 My problem is maybe similar to this, but another situation. Consider this list in input : ['ACCCACCCGTGG','AATCCC','CCCTGAGG'] And the other input is n,n is a number, the dimension of the substring in common in every element of the list. So the output has to be the maximum occorence substring with the number of occorences, similar to this: {'CCC' : 4} 4 becouse in the first element of list are twice, and one time in the other two strings. CCC becouse is the longhest substring with 3 elements

问题 I am trying to apply style to the text selected by the user(mouse drag) for which I need to get the start and end index of the selected text. I have tried using "indexOf(...)" method. but it returns the first occurrence of the selected substring. I want the actual position of the substring with respect to the original string. For example.., if I select the letter 'O' at position 3 [YOL O Cobe], I expect the index as 3 but the indexOf() method returns 1 which is the first occurrence of 'O' in

问题 I have a column in a larger dataset that looks like: Name ---- Mr. John Doe Jack Daw Prof. Charles Winchester Jane Shaw ... etc. (Names anonymized) Basically, its a list of names that have prefixes mixed in. All prefixes end with a dot. So far, the prefixes have been limited to: Mr. Mrs. Ms. Dr. and Prof. The output I would like is: Name ---- John Doe Jack Daw Charles Winchester Jane Shaw ... etc. Ideally, I would like a solution that relies on the position of the dot instead of having to
