The following pseudocode shows a subroutine designed to calculate the total sum of all below-freezing temperatures (temperatures less than 0) recorded in an array of daily temperatures.
SUBROUTINE calculateFreezingTotal(temps)
p ← 0
j ← 0
WHILE j < LENGTH(temps)
IF temps[j] < 0 THEN
p ← p + temps[j]
ENDIF
j ← j + 1
ENDWHILE
RETURN p
ENDSUBROUTINE
The identifier for the variable p in the subroutine is not a good choice.
State a better identifier for this variable that makes the algorithm easier to read and understand.
