Write a static method called bothstart that allows the user to input two strings and returns the string that is the longest substring s such that both inputs start with s.

for example,

bothstart( "radar dish", "radical food" ) returns "rad"

bothstart( "radar disk", "disk radar" ) returns ""

bothstart( "radar installation", "" ) returns ""

bothstart( "mendacious", "mendicant" ) returns "mend"

bothstart( "frankly", "frank" ) returns ""

Explanation:

Let's start with creating a static method bothStart() with two String type parameters, text1 & text2 (Line 1).  

Create a String type variable, s, which will hold the value of the longest substring that both inputs start with the same character (Line 2).

There are two possible situation here: either text1 longer than text2 or vice versa. Hence, we need to create if-else statements to handle these two position conditions (Line 4 & Line 13).

If the length of text1 is longer than text2, the for-loop should only traverse both of strings up to the length of the text2 (Line 5). Within the for-loop, we can use charAt() method to extract individual character from the text1 & text2 and compare with each other (Line 15). If they are matched, the character should be joined with the string s (Line 16). If not, break the loop.

The program logic from (Line 14 - 20) is similar to the code segment above (Line 4 -12) except for-loop traverse up to the length of text1 .

At the end, return the s as output (Line 21).

answer; technician (b) is wrong; so im thinking technician (a) is correct; good luck
