Answer: Plastic, metal, rubber, wiring, electricity, technology, wifi,
Explanation: You need PLASTIC to make a frame for the computer. METAL
to make an exoskeleton under the plastic frame. RUBBER to hold those loose wires and to make sure the electricity doesn't escape and shock you. ELECTRICITY to charge and make the computer runs. Technology is used for you to log in and out of your computer and WIFI to make sure it doesn't lag.
Code:
def myAppend( str, ch ):
# Return a new string that is like str but with
# character ch added at the end
return str + ch
def myCount( str, ch ):
# Return the number of times character ch appears
# in str.
# initiaalizing count with 0

# iterating over every characters present in str
for character in str:
# incrementing count by 1 if character == ch
if character == ch:
count += 1
# returning count
return count

# str1 followed by the elements of str2, in the same
# order they appear in str2.
# concatenating both strings and returning its result

# Return the character in str with the lowest ASCII code.

# storing first character from str in char

# returning -1 otherwise
return -1
def myRemove( str, ch ):

# removed. If there is none, return str.
# returning str if ch is not present in str

if char == ch:

# incrementing pos by 1

# returning strig excluding first occurence of ch

def myRemoveAll( str, ch ):

# removed. If there are none, return str.
# creating an empty string
string = ""
# iterating over each and every character of str
for char in str:
# if char is not matching with ch then adding it to string
if char!=ch:

# returning string
return string
def myReverse( str ):
# Return a new string like str but with the characters
# in the reverse order.
return str[::-1]

I hope this helped ^_^
I have a kindle paper white that I downloaded all of my avalible textbook onto if that helps I find it much better then carrying around a bunch of textbooks
People lump and dismiss improvement efforts that fall short of categorical change—despite improving Psychological Science.
<h3>What is Psychological Science?</h3>
Psychological Science is said to be the source for examining or knowing findings on topics that are linked to cognitive, social, developmental, as well as health psychology.
Note that based on an experiment, participants were said to have lumped together absolute failures but they do not do so for absolute successes, and thus it is highlighting a special blindness to gradations of badness.
Hence, People lump and dismiss improvement efforts that fall short of categorical change—despite improving Psychological Science.
