Note: Array class with its build in methods are not allowed. Predefined methods from the String class are allowed: substring, find, charAt, and

isEmpty.

Define a method called SecondLowest. We pass an array when called it and print the second lowest number in that array. The array must have at least $2$ numbers, shows a message $$Invalid size$$ when not applied.

Example $1$:

Enter Array Size: $5$

Enter Number $1$: $100$

Enter Number $2$: $155$

Enter Number $3$: $40$

Enter Number $4$: $78$

Enter Number $5$: $90$

Second lowest number is: $78$

Example $2$:

Enter Array Size: $1$

Invalid size
