Before the use of technology such as computers, information was documented through papers separated in folders. This was a very long and complicated process as people would have to find information by hand, sorting through countless documents. Now, it is much easier and neater to keep information. It can be as easy as digitally searching for someone's name and the computer will sort through countless documents, finding the one you need almost instantly. It is also much less wasteful and safe, as before computers, the use of paper was the only way to permanently keep information, also making documents vulnerable to being lost or stolen.
Answer:
888 + 88 + 8 + 8 + 8 = 1000
Explanation:
Required
Add up to 1000 using only digit 8
There is no straight way to answer this question; so, we make use of trial by error method to arrive at our solution.
After several trials, I found out that:
888 + 88 + 8 + 8 + 8 = 1000
Answer:
In Python:
import os.path
from os import path
fname = input("Filename: ")
if path.exists(fname):
with open(fname) as file_in:
lines = []
for line in file_in:
lines.append(line.rstrip('\n'))
f = open("stat.txt","r+")
f.truncate(0)
f = open("stat.txt", "a")
f.write("Names\tTotal\tSubjects\tAverage\n")
for i in range(len(lines)):
rowsum = 0; count = 0
nm = lines[i].split()
for j in nm:
if (j.isdecimal()):
count+=1
rowsum+=int(j)
average = rowsum/count
f.write(nm[0]+"\t %3d\t %2d\t\t %.2f\n" % (rowsum, count, average))
f.close()
else:
print("File does not exist")
