How do you know if a number is a perfect square without Squarert?

Program to check number is perfect square or not without sqrt function in Python

  1. temp := a list of all numbers from start to stop.
  2. k := middle element of temp.
  3. k_squared := k * k.
  4. if k_squared is same as n, then. return True.
  5. if k_squared > n, then. start := temp[0] stop := k – 1.
  6. otherwise, start := k + 1.

How do you check a number is square or not?

Fastest way How to check if a number is a Perfect Square or not

  1. Digital roots are 1, 4, 7 or 9.
  2. If unit digit ends in 5, ten’s digit is always 2.
  3. If it ends in 6, ten’s digit is always odd (1, 3, 5, 7, and 9) otherwise it is always even.
  4. If a number is divisible by 4, its square leaves a remainder 0 when divided by 8.
