Find All KDistant Indices in an Array


Here’s a stepbystep explanation of the solution:
Create a List of Indices: Identify the indices in
nums
where the value is equal tokey
.Initialize Result List: Initialize an empty list
result
to keep track of the kdistant indices.Iterate through
nums
: For each indexi
ofnums
, check if it is a kdistant index by comparing with the identified indices ofkey
. Check kDistance: If there exists an index
j
in the list of key indices such that the differencei  j
is less than or equal tok
, then add indexi
to the result.
 Check kDistance: If there exists an index
Return the Result: Finally, return the
result
list which consists of all the kdistant indices sorted in increasing order.
The code first finds the indices of key
in nums
and then iterates through each index of nums
to check if it is a kdistant index by comparing with the key indices. If found, the index is added to the result. Finally, the result is returned.
