1) Given the strings s1 and s2 that are of the same length, create a new string consisting of the first character of s1 followed by the first character of s2, followed by the second character of s1, followed by the second character of s2, and so on (in other words the new string should consist of alternating characters of s1 and s2). For example, if s1 contained "hello" and s2 contained "world", then the new string should contain "hweolrllod". Associate the new string with the variable s3.

2) Given the strings s1 and s2 that are of the same length, create a new string consisting of the last character of s1 followed by the last character of s2, followed by the second to last character of s1, followed by the second to last character of s2, and so on (in other words the new string should consist of alternating characters of the reverse of s1 and s2). For example, if s1 contained hello" and s2 contained"world", then the new string should contain "odlllreohw". Assign the new string to the variable s3.

3) Given the strings s1 and s2, not necessarily of the same length, create a new string consisting of alternating characters of s1 and s2 (that is, the first character of s1 followed by the first character of s2, followed by the second character of s1, followed by the second character of s2, and so on. Once the end of either string is reached, no additional characters are added. For example, if s1 contained "abc" and s2contained "uvwxyz", then the new string should contain "aubvcw". Assign the new string to the variable s3.

4) Given the strings s1 and s2, not necessarily of the same length, create a new string consisting of alternating characters of s1 and s2 (that is, the first character of s1 followed by the first character of s2, followed by the second character of s1, followed by the second character of s2, and so on. Once the end of either string is reached, the remainder of the longer string is added to the end of the new string. For example, if s1 contained "abc" and s2 contained "uvwxyz", then the new string should contain "aubvcwxyz". Associate the new string with the variable s3.
