Hi, to me problem statement is super unclear and vague, can someone explain more with more testcases?
This problem is about the version of any app.
for example for an app
version1 = 1.1
version2 = 2.2;
or version1 = 2.2 and version2 = 1.1;
`if( version1 > version2)
else if( version1 < version2)
else return 0;`
finally we have to insure that
case 1: if version1 is newer compare to version2 then return 1 .
case 2: if version1 is older compare to version2 then return -1 .
case 3: if version1 and version2 are same then return 0 .
