Examine the following pseudocode. IF A = TRUE THEN IF B = TRUE THEN IF C = TRUE THEN CALL Sub1() ELSE CALL Sub2() ENDIF ENDIF ELSE IF B = TRUE THEN IF C = TRUE THEN CALL Sub4() ELSE CALL Sub3() ENDIF ELSE IF C = FALSE THEN CALL Sub3() ELSE CALL Sub4() ENDIF ENDIF ENDIF A programmer wants to re-write the pseudocode as four separate IF...THEN...ENDIF statements, each containing a single CALL statement. This involves writing a single, simplified logic expression as the condition in each statement. Write the amended pseudocode. 1 2 3 4 [4]
