hey harshita,

best government college in Aktu are as follows

• IET Lucknow
  
• KNIT Sultanpur
• BIT bundelkhand

Now if we talk about infrastructure, so every gov. college has an average infrastructure. as they are very old buildings,placement rate is good there. some of good private colleges as AKG or JSS have nice infrastructure.

so for future advancement( like internship, locality,residency) 

among all these colleges IET will be best.. but you may not get cs there so.. go for any other branch and if you get good percentage in 1st year you can change your branch as well.

good luck
