When I try to solve a problem a little bit higher above my ability I face a lot of problem. I get stuck then read editorial and solve it later. But what should I do or you would do in this situation:

1. When you can't generate the idea for a specific problem.
2. Then you cant' understand still after reading the editorial.
3. Then you still can't understand solution reading other's code?
4. There's no one you know that you can take help from.

Artist: John Denver.

All my bags are packed I'm ready to go I'm standin' here outside your door I hate to wake you up to say goodbye But the dawn is breakin' It's early morn The taxi's waitin' He's blowin' his horn Already I'm so lonesome I could die So kiss me and smile for me Tell me that you'll wait for me Hold me like you'll never let me go 'Cause I'm leavin' on a jet plane Don't know when I'll be back again Oh babe, I hate to go There's so many times I've let you down So many times I've played around I tell you now, they don't mean a thing Ev'ry place I go, I'll think of you Ev'ry song I sing, I'll sing for you When I come back, I'll bring your wedding ring So kiss me and smile for me Tell me that you'll wait for me Hold me like you'll never let me go 'Cause I'm leavin' on a jet plane Don't know when I'll be back again Oh babe, I hate to go Now the time has come to leave you One more time Let me kiss you Then close your eyes I'll be on my way Dream about the days to come When I won't have to leave alone About the times, I won't have to say Oh, kiss me and smile for me Tell me that you'll wait for me Hold me like you'll never let me go 'Cause I'm leavin' on a jet plane Don't know when I'll be back again Oh babe, I hate to go But, I'm leavin' on a jet plane Don't know when I'll be back again Oh babe, I hate to go Songwriters: John Denver
