• What does program (Snake) knows

  • How to allocate memory
  • It know + – * / % < > <= => ==
  • One memory location for index
  • One memory location for result
  • One memory location for maxValue

• Language: Hi Snake , remember 1 and call it as index remember 0 and call it as result remember 20 and call it as maxValue

  Import Location:: check if index%2 == 0 if yes add index to result now increment index (index = index +1) if index <= max Goto Import Location:: display result

Problem : Try to find number of letters which are repeated more than one and its count in the following Text

Hello World o/p: l = 3 o = 2

knows about : length  []

• Solution:

Hi snake, remember Hello World and call it as message

start with index = 0 till index < length(message)
get message[0] and store it in temp 
compare it with all the other locations and maintain count
if count is zero ignore and continue scanning
else  print  letter = count
