static boolean prime(int n){
int c=0;
for(int i=0;i<n;i++){
if(n%i==0){
c++;
}
}
if(c==2){
return true;
}else{
return false;
}

public static void main(String[] args){
int[] arr={2,5,7,6,8,11,14,13,50};
for(int i=0;i<arr.length;i++){
if(prime(arr[i]){

Question: We would like to design and implement a programming solution to the reader-writer problem using semaphores in C language under UNIX. We assume that we have three readers and two writers processes that would run concurrently. A writer is to update (write) into one memory location (let’s say a variable of type integer named temp initialized to 0). In the other hand, a reader is to read the content of temp and display its content on the screen in a formatted output. One writer can access the shared data exclusively without the presence of other writer or any reader, whereas, a reader may access the shared memory for reading with the presence of other readers (but not writers).

Write a C program to print look and say sequence? For example if u get the input as 1 then the sequence is 11 21 1211 111221 312211 12112221 .......(it counts the no. of 1s,2s etc which is in successive order) and this sequence is used in run-length encoding.
