0 1 .2 The POSITION subroutine returns the position of the first occurrence of a character in a
string.
For example:
POSITION("Godzilla vs. Kong", "o") would return 1
POSITION("Godzilla vs. Kong", "z") would return 3 letter and film
are variables used in the algorithm in Figure 1.
Complete the pseudo-code statement to find the position of the first occurrence of the contents
of letter in film and store this position in the variable location
