The pseudocode represents an algorithm. The pre-defined function DIV gives the value of the result of integer division. For example, Y = 9 DIV 4 gives the value Y = 2 The pre-defined function MOD gives the value of the remainder of integer division. For example, R = 9 MOD 4 gives the value R = 1 First ← 0 Last ← 0 INPUT Limit FOR Counter ← 1 TO Limit INPUT Value IF Value >= 100 THEN IF Value < 1000 THEN First ← Value DIV 100 Last ← Value MOD 10 IF First = Last THEN OUTPUT Value ENDIF ENDIF ENDIF NEXT Counter
