54:
you can load the source file to memory at the beginning of
the run using mmap(), or using one of the countless methods
to read from file in C and storing the data in a string
array, then it won't matter if the file is deleted, you can
always re-create it using the data in the process memory.

53:
int checkBits(x){
numOfOnes=0;
do{
if((x%2)!=0)
{numOfOnes++;}
x=x/2;
}while (x!=0);
return numOfOnes;
}
55:
int checkPower(x){
if(checkBits(x)==1)
{return 1;}
else{return 0;}
