6) (4 pts) Give a regular expression for a certain type of scientific notation forreal numbers on which the a. The number can be preceded by a “+" or "-“ sign or the sign may be absent. C. The number may be followed by an exponent field of the form e"+"yiy2 ore"-"Viy2, where y and y2 can be any digit in (0,1,2,3,4,5,6,7,8,9). (Note: With this convention "+"is the sign associated with the scientific number and+the operator of the regular expression.)

Explanation / Answer

6)

a) Answer : ("+" + "-" +"")(0+1+2+3+4+5+6+7+8+9)+

explanation:

first

number can be formed from any of 0,1,2,3,4,5,6,7,8,9, so (0+1+2+3+4+5+6+7+8+9)

and they can be any number of times so...(0+1+2+3+4+5+6+7+8+9)* here + means string length at least one

now

at the starting of the number we can have "+" or "-" or "" empty

so ("+" + "-" +"")

b)Answer : (1+2+3+4+5+6+7+8+9)(0+1+2+3+4+5+6+7+8+9)+

explanation:

here given c can't be 0

so removing 0, (1+2+3+4+5+6+7+8+9)//and c length is one

then b1b2b3....bn

min length is 1

so (0+1+2+3+4+5+6+7+8+9)+

c)Answer: (0+1+2+3+4+5+6+7+8+9)+(e"+"+e"-")(0+1+2+3+4+5+6+7+8+9)(0+1+2+3+4+5+6+7+8+9)

explanation:

(0+1+2+3+4+5+6+7+8+9)+(e"+"+e"-")(0+1+2+3+4+5+6+7+8+9)(0+1+2+3+4+5+6+7+8+9)

number exponent Y1 y2
