Sum of Prime Numbers from M to N

Given two integers M and N, write a program to print the sum of prime numbers from M to N.Input

The first line of input will contain a positive integer (M).

The second line of input will contain a positive integer (N).Output

The output should be a single line containing the sum of prime numbers from M to N.Explanation

For example, if the given M and N are 5 and 11, as all the prime numbers from 5 to 11 are 5, 7, and 11. So the output should be sum of these primes (5+7+11), which is 23.

Similarly, if the given numbers are M is 18 and N is 40, as all the prime numbers from 18 to 40 are 19, 23, 29, 31,and 37. So the output should be sum of these primes (19+23+29+31+37), which is 139.

Given a string, write a program to move all the numbers in it to its start.Input

The input will contain a string A.Output

The output should contain a string after moving all the numbers in it to its start.Explanation

For example, if the given string A is "1good23morning456", the output should be "123456goodmorning", as it contains numbers at the start.

Sample Input 1

1good23morning456

Sample Output 1

123456goodmorning
