how do I sort dictionaries by value then by key?

Insection sort what does value := A[i] mean?

• insertionSort(array A) { This procedure sorts in ascending order. } begin for i := 1 to length(A)-1 do begin value := A[i]; j := i - 1; done := false; repeat { To sort in descending order simply reverse the operator i.e. A[j] < value } if A[j] > value then begin A[j + 1] := A[j]; j := j - 1; if j < 0 then done := true; end else done := true; until done; A[j + 1] := value; end; end; what does value := A[i] do , does it mean make the value to what ever is in {i}

• Answer:

  A is an array, essentially an ordered list of values. Individual values in that list are accessed by indexing the array, which is what the brackets are about. A[0] is the first value, A[1] is the second value, and so on. The index doesn't have to be a specific number. It can be a variable or other expression to compute the index number. That's what A[i] and A[j+1] are about. Each uses the current value of the variable (i or j in these cases) to calculate the index. So, if that's what you meant by "do what ever is in {i}", then you're right.
