Question

Accepted Answer

Javascript code to find frequency of characters in a sentence and difference between dynamic and static initialization.

To find frequency of characters in a sentence, create an object and iterate over each character in the sentence. Increment the count of each character in the object.
Dynamic initialization refers to initializing a variable at runtime, while static initialization refers to initializing a variable at compile time.
Example of dynamic initialization: int x = new int[5]; Example of static initialization: int x[] = {1, 2, 3, 4, 5};

Accepted Answer

Answer 1:- function countCharacterFrequency(sentence) {

const frequencyMap = {};

// Loop through each character in the sentence

for (let char of sentence) {

// Ignore spaces

if (char !== ' ') {

// Update the frequency in the map

frequencyMap[char] = (frequencyMap[char] || 0) + 1;

}

// Output the character frequencies

for (let char in frequencyMap) {

console.log(`${char}: ${frequencyMap[char]}`);

}

// Example usage

const inputSentence = "Hello, World!";

countCharacterFrequ

ency(inputSentence);

Answer 2:- Dynamic initialization occurs at runtime and involves assigning values to variables during program execution, often using input or calculated values. Static initialization, on the other hand, happens at compile time and involves assigning values to variables before runtime, typically using constant values or expressions.

In simpler terms, dynamic initialization occurs while the program is running, whereas static initialization takes place before the program starts executing.
