I have many strings which are represent some objects:
tua15
tub15
tuc15
[...]
tuk15
tul15
tua16
tub16
"tu" is constant, a,b,c...k,l represent month and last two digits represent year (2015, 2016). When I sort this strings I get:
tua15
tua16
tub15
tub16
tuc15
tud15
[...]
How to sort this strings by letters with corelation with year number?
