Oblivious Update

Request a New Nada Example

Obliviously update an element of a list if it exists.

Description

Similarly to our linear scan example that checks whether a specific value old_value is present in a list, we now want to update the value to a new_value (if it exists).

For example in a list of SecretIntegers [1, 2, 3, 4, 5], old_value = 2, and old_value = 6, the list will become [1, 6, 3, 4, 5].

@jimouris @oceans404 I'll take up this issue. Should i replace all the old_value to new_value present in the list.

Ex: [1, 2, 3, 4, 5, 2] old_value = 2 new_value = 6 => [1 , 6, 3, 4, 5, 6]
