Input Validation: making sure that the data input by the user is acceptable e.g. in a suitable format and within the upper and lower limits of the data required by the software

RECEIVE userInput FROM (INTEGER) KEYBOARD
WHILE userInput < lowerLimit OR userInput > uperLimit DO
    SEND “Input must be between” & lowerLimit & “and” & upperLimit TO DISPLAY
    RECEIVE userInput FROM (INTEGER) KEYBOARD
END WHILE

Linear Search (efficient): sets a Boolean variable to false initially and uses an unconditional loop to set it to true when the item is found; the loop terminates when the item is found or the end of the array is reached

RECEIVE itemToFind FROM (INTEGER) KEYBOARD
SET found to false
SET arraySize to higestIndex
SET counter TO 0

WHILE counter <= arraySize AND found = false
    SET counter to counter + 1
    IF array[counter] = itemToFind THEN
        found=true
    END IF
END WHILE

IF found = true THEN
    SEND itemToFind & “found at position” & counter TO DISPLAY
ELSE
    SEND “Item not found” TO DISPLAY
END IF

Finding Minimum: sets an initial value to the first item in the array then compares it to the remaining items

SET maxiumValue to numbers[0]

FOR counter FROM 1 TO 9 DO
    IF maximumValue < numbers[counter] THEN
        SET maximumValue to numbers[counter]
    END IF
END FOR

SEND “The largest value was” & maximumValue to DISPLAY

Finding Maximum: sets an initial value to the first item in the array then compares it to the remaining items

SET miniumValue to numbers[0]

FOR counter FROM 1 TO 9 DO
    IF minimumValue > numbers[counter] THEN
        SET minimumValue to numbers[counter]
    END IF
END FOR

SEND “The smallest value was” & minimumValue to DISPLAY

Count Occurrences: sets a total to zero at the beginning and increments it as items are found to match the search item

RECEIVE itemToFind FROM (INTEGER) KEYBOARD
SET numberFound to 0

FOR EACH number FROM numbers DO
    IF number=itemToFind THEN
        SET numberFound to numberFound+1
    END IF
END FOR EACH

SEND “There were” & numberFound & “occurreneces of” & itemToFind & “in the list” TO DISPLAY
