The variables site, dept, and code are assigned values as shown below:
site ← 'Southampton'
dept ← 'Aerospace'
code ← 'SOT-102A'
A programmer executes the following sequence of instructions to format a database key:
r1 ← SUBSTRING(5, 4, dept)
r2 ← SUBSTRING(0, 5, site)
r3 ← SUBSTRING(3, 1, code)
result ← r1 + r3 + r2
y ← LEN(result)
What is the value of the variable y after these statements are executed?
Assume that the pseudocode SUBSTRING(startPosition, numberOfCharacters, string) uses 0-based indexing.
