List input$\_$list contains integers read from input, representing a decreasing sequence of data values. min$\_$diff measures the minimum difference between two neighboring values in the sequence, and is initialized with None. For each index i of input$\_$list from $1$ through the last index:

Compute variable neighbor$\_$diff as the element at index i $-1$ minus the element at index i$.$

Output the element at index i $-1,$ followed by $\text{'}-\text{'},$ the element at index i$,\text{'}=\text{'},$ and the value of neighbor$\_$diff.

Assign min$\_$diff with the minimum value of neighbor$\_$diff computed in all the iterations.

Output 'Index $\text{'},$ followed by the element's index, $\text{'}$: $\text{'},$ and the element's value.

Increase sum$\_$accepted by each such element's value.
