Functions-Basic Programming Concepts With psudo Code

Function is a block of code or sub program used to divide the large programs into small parts.Mainly used for Debug Process.

Use of functions

used to reduce the lines of code
easy to debug
Reuse ability

Syntax

 return_type function_name([argument1],[argument2]...)
 {
  //statement or block of code;
 } 
 function_name([argument1],[argument2]...);

Example,

main() { fun(); } fun() { printf("\n function is called"); }

Types Of Functions

Function With Argument And Return Value
Function Without Argument And Return Value
Function With Argument And Without Return Value
Function Without Argument And Return Value

LPS(Longest Prefix Which Is Also Suffix) Array Generation Using Java

import java.util.* ; //Longest Prefix Which Is Also Suffix Which Is Used To Found a Pattern Through Avoid Repeated Characters in Given String. We Will Discuss KMP ALGORITHM TO Find A Pattern In Given String Latter. class lbs{ public static void main( String [] args){ Scanner in= new Scanner(System.in); //Get Input From User String s=in.nextLine(); //Convert String Into Char Array char [] ch=s.toCharArray(); int n=s.length(); int [] lbsArr= new int [n]; int j= 0 ,i= 1 ; lbsArr[ 0 ]= 0 ; //LPS ARRAY ALGORITHM /* i=1; j=0; string s="aaab" while i<n if s[i]==s[j]: lpsArr[i]=j; j=j+1 i=i+1 else: if j==0: lbsArr[j]=0 i=i+1 else: ...

Run Length Encoding | Programming In Java

Given a string, Your task is to complete the function encode that returns the run-length encoded string for the given string. eg if the input string is “wwwwaaadexxxxxx”, then the function should return “w4a3d1e1x6″. You are required to complete the function encode that takes only one argument the string which is to be encoded and returns the encoded string. Example 1: Input: str = aaaabbbccc Output: a4b3c3 Explanation: a repeated 4 times consecutively b 3 times, c also 3 times. Example 2: Input: str = abbbcdddd Output: a1b3c1d4 Your Task: Complete the function encode() which takes a character array as an input parameter and returns the encoded string. Expected Time Complexity: O(N), N = length of a given string. Expected Auxiliary Space: O(1) Constraints: 1<=length of str<=100 Solution: import java.util.*; class RLEncoding { public static void main(String[] args) ...

Sum Of Given Array Elements

public static void main( String [] args){ int [] arr={ 1 , 2 , 3 , 4 , 5 , 6 }; int n=arr.length; int sum= 0 ; for ( int i= 0 ;i<n;i++){ sum+=arr[i]; } System.out.println(sum); } } Java Programming /* Sum Of Given Array Elements Time Complexity O(n) */ class sumOfArray{
