Memory

Memory Heap

• Where memory allocation for global variables happens (e.g., variables, arrays, hashmaps)

a = 1

• Memory Leak
• Whenever the memory is allocated, but forgotten to be deallocated when it is not used anymore
• It can be solved by manually deallocating it or by a garbage collector

Call Stack

• Where we keep track of function calls

• e.g., in a recursion the call stack is increased until the base case

• Stack Overflow

• When the number of stacks in the call stack is increased indefinitely
• Usually by bad recursions
