Question 29

An algorithm is used to parse telemetry data from an oceanographic research buoy.

Figure 2

reading ← ""
k ← 0
WHILE raw_payload[k] ≠ "K" AND k < 8
    reading ← reading + raw_payload[k]
    k ← k + 1
ENDWHILE
is_valid ← False
IF reading ≠ "" AND k < 8 THEN
    is_valid ← True
ENDIF

State the data type of the variable is_valid in the algorithm in Figure 2.
