Getting the indexes of duplicate elements in arrays (Ruby) -


i have array in ruby has duplicate elements. e.g.:

fruits = ["apples", "bananas", "apples", "grapes", "apples"]

when following:

fruits.index("apples") # returns 0

i first occurrence of "apples" is, in case, fruits[0]. there way can run similar above code , indexes of other occurrences of "apples"? if can't run similar above code, how else can indexes of duplicate elements?

taking page procedural languages, write:

fruits.each_index.select { |i| fruits[i]=="apples" }   #=> [0, 2, 4]
