Why does this code have complexity O(1)?

function logAtMost5(n) {
  for ( let i = 1; i <= Math.min(5,n); i   {
    console.log(i)
  } 
}

CodePudding user response：

This function does at most 5 iterations. Which is a constant.

A constant has O(1) complexity.

If there was n instead of Math.min(5,n), it would have n iterations which would be linear O(n).

CodePudding user response：

Simply because the for loop will not iterate more than 5 times, it's iterations will not exceed a fixed constant.
