The mode is the value that appears most often in a set of data values. For example, in a set of numbers: {1, 2, 2, 3, 4, 7, 9} the mode is 2 (it occurs the most frequently).
Now, suppose you have the slice nums of integer numbers:
nums := []int{1, 3, 5, 5, 5, 7, 9, 11}
Write below the slice expression that creates a subslice n with all the repeated slice elements that make up the mode of nums.
Take notice that your answer should follow the format of n := nums[?:?], where question marks should be replaced with simple int numbers.
