Q7. Looking at the following commands, describe what is happening.

git checkout feature-user-location
git cherry-pick kj2342134sdf090093f0sdgasdf99sdfo992mmmf9921231

Explanation:

‘git checkout feature-user-location’ switches to the ‘feature-user-location’ branch. ‘git cherry-pick kj2342134sdf090093f0sdgasdf99sdfo992mmmf9921231’ applies the changes from the specified commit (‘kj2342134sdf090093f0sdgasdf99sdfo992mmmf9921231’) to the current branch (feature-user-location). This effectively copies the commit from its original branch to the feature-user-location branch. So, this sequence of commands is cherry-picking a specific commit onto the feature-user-location branch.
