Question

write a program to create 2 function int reverse(int n) and int face print whether a number is twisted prime(empirp number) or not the number is prime where as its reverse is also prime​

Answer 1

Answer:

STEP 1: START

STEP 2: DEFINE n, reverse, flag

STEP 3: SET sum = 0

STEP 4: ENTER n

STEP 5: REPEAT STEP 6 to 8 UNTIL (n!=0)

STEP 6: reverse = n%10

STEP 7: sum = sum*10 + reverse

STEP 8: n = n/10

STEP 9: SET flag =0

STEP 10: REPEAT STEP 11 UNTIL j<=sum/2

STEP 11: if(sum%j)==0

then

set flag = 1

break

STEP 12: if(flag==0)

then PRINT "yes"

else

PRINT "no"

STEP 13: END
