Self Doubts:
Q. An SJF algorithm is simply a priority algorithm where the priority is : A) predicted next cpu burst B) The inverse of the predicted next cpu burst C) the current cpu burst D)anything the user want so in this what will be the ans it's a) or c) ? I confused with these two options.please gives proper explanation.
