Hello Srinivas The traditional way to achieve this in go (as showcased here <https://golang.org/pkg/sort/#example_> and here <http://www.programming-idioms.org/idiom/28/sort-by-a-property/160/go>) is, to : - declare a named type of slice - implement 3 methods Len, Less, Swap <https://golang.org/pkg/sort/#Interface> - call sort.Sort <https://golang.org/pkg/sort/#Sort>
(each attribute age, name, sal, needs its own type declaration and 3 method implementations). Since Go 1.8, we can achieve basically the same with much less boilerplate code (as showcased here <https://golang.org/pkg/sort/#example_Slice> and here <http://www.programming-idioms.org/idiom/28/sort-by-a-property/1936/go>) : - implement 1 func "less" having type func(i, j int) bool - call sort.Slice <https://golang.org/pkg/sort/#Slice> (each attribute age, name, sal, needs its own "less" func). I suggest the latter.
