Answer:
When the element is not found we return -1.
Explanation:
When we use binary search we use BinarySearch() method of an array or list type when the element is found we return the index of the element if found if the element is not found we return -1.
We can decode this value since it is less than 0 and the indexing of arrays and lists starts with 0 upto the size-1.So -1 index is not present in the array or list.We have to check if the index is < 0 then the element is not present in the array or list.
for ex:-
if(index<0)
{
System.out.println("Element is not present in the array");
}
Answer:
The change in complex systems can be explained according to the relationship of the environment where the system is implemented.
The system environment is dynamic, which consequently leads to adaptation to the system, which generates new requirements inherent to changes in business objectives and policies. Therefore, changing systems is necessary for tuning and usefulness so that the system correctly supports business requirements.
An example is the registration of the justification of the requirements, which is a process activity that supports changes in the system so that the reason for including a requirement is understood, which helps in future changes

Solution :

#include 
//Converts

* hexadecimal
Binary(char* hexdec)
{
long

char *string = 
(sizeof(char) * 9);
while (hexdec[i]) {
//Simply assign binary string for each hex char.
switch (hexdec[i]) {
strcat(string, "0000");
break;

break;
case 'E':
case 'e':
strcat(string, "1110");

case 'F':
case 'f':

default:
printf("\nInvalid hexadecimal digit %c",

}
return string;
}
int main()
{ //Take 2 strings
char *str1 =hexadecimalToBinary("FA") ;
char *str2 =hexadecimalToBinary("12") ;
//Input 2 numbers p and n.
int p,n;
scanf("%d",&p);
scanf("%d",&n);
//keep j as length of str2
int j=strlen(str2),i;
//Now replace n digits after p of str1
for(i=0;i<n;i++){
str1[p+i]=str2[j-1-i];
}
//Now, i have used c library strtol
long ans = strtol(str1, NULL, 2);
//print result.
printf("%lx",ans);
return 0;
