Concept explainers

Concept of memory addresses in pointers

The concept of pointers in high-level languages was introduced in C programming. Pointers are simply the variables that are used to store memory addresses of another variable. These special variables are generally used in the languages such as C Programming and C++ Programming, where it allows the programmer to work more deeply with memory and its addresses.

Practice / Frequency of Characters Write a method that returns the frequency of each characters of a given String parameter. If the given String is null, then return null If the given String is empty return an empty map Example input: output: empty map explanation: input is empty Example input: null output: null explanation: input is null. Since problem output is focused on the frequency we can comfortably use Map data structure. Because we can use characters as key and the occurrences of them as value. Example input: responsible output: {r=1, e=2, s=2, p=1, o=1, n=1, i=1, b=1, l=1} explanation: characters are keys and oc values ences are
