Problem Statement

Given a string of integers, write a program to generate an output string as follows

i$)$ From the input integers, filter the integers that are perfect squares. Ex: $1,4,9,16,25,36,49,64,81,100$dots

ii$)$ For each perfect square obtained from step $1,$ find its factorial. If the factorial of the number is trailing by zeros, three digits present before the trailing zeros should be appended to output string. If not trailing by zeros append last three digits to output string. If there is a preceding zero, it is ignored.

i$.$ If the number is $2$ then $22,$ it does not have any trailing zeros and there is only one digit in it$,$ so append $2$ to output.

ii$.$ If the number is $5$ then $5120,$ it has one trailing zero and before the trailing zero there are only two digits present so append $12$ to output.

iii. If the number is $9$ then $9362880,$ it has one trailing zero, before trailing zero there are five digits present, so consider three digits before trailing zero that is $288$ and append to output.

iv$.$ If the number is $12$ then $12479001600,$ it has two trailing zeros, before trailing zeros there are seven digits present, so consider three digits before trailing zero that is $016$ as $0$ is preceded here, $0$ is ignored and $16$ is appended to output.

iii$)$lf there are no positive perfect squares in the input string print $-1$

Example:

Input String: $2,4,6,9,35,100$

Perfect squares from input are: $4,9,100$

Factorial of the perfect squares are:

$4-24($Factorial is not trailing by zero. Hence, will be considered as it is in Output$).$

$9-362880($Factorial is trailing by zero. Hence, last $3$ digits before zero $-288,$ will be considered$)$

$100-$

$93326215443944152681699238856266700490715968264381621468592$

$($Factorial is trailing by zero. Hence, last $3$ digits before zero$-864,$ will be considered$)$

Hence, Output will be: $24,288,864.$

Input Format: Input string contains all the numbers separated by comma.

Output Format: All the values in output string should be printed in the form of single string, where values should be separated by comma. And in case, there are no positive perfect squares then $-1$ should be printed.
