  - by PPTim

  Hi, Say there is a dict variable that grows very large during runtime- up into millions of key:value pairs. Does this variable get stored in RAM,effectively using up all the available memory and slowing down the rest of the system? Asking the interpreter to display the entire dict is a bad idea, but would it be okay as long as one key is accessed at a time? Tim

• How to implement three stacks using a single array.

  - by buried-shopno

  Hi, I came across this problem in an interview website. The problem asks for efficiently implement three stacks in a single array, such that no stack overflows until there is no space left in the entire array space. For implementing 2 stacks in an array, it's pretty obvious: 1st stack grows from LEFT to RIGHT, and 2nd stack grows from RIGHT to LEFT; and when the stackTopIndex crosses, it signals an overflow. Thanks in advance for your insightful answer.
