ios - How can I set the height of my first UITableViewCell higher than the others? -


i trying in viewdidload():

func tableview(_ tableview: uitableview, heightforrowat indexpath: indexpath) -> cgfloat {     if indexpath.row == 0 {         return 300.0     }     return 100.0 }

but has no effect

in swift 3 write code in following way height row tableview delegate method do. not write inside of viewdidload method, can write in outside of viewdidload method

import uikit

class profileviewcontroller: uiviewcontroller,profileviewcontrollerdelegate {      //mark: - outlet -      @iboutlet weak var tblview: uitableview!      //mark: - view life cycle -     override func viewdidload() {      }      //mark: tablview delegate     func tableview(_ tableview: uitableview, heightforrowat indexpath: indexpath) -> cgfloat {         if indexpath.row == 0 {             return 300.0         }         return 100.0

}

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
