(back to top)

challenge of the week

• Improve Shorting hat Function For edge cases Click here
  • For person with third name
  • Two person with the same First name
• Improve stack.js from week-2
  • LastRemove function is not Working. it should return the last pop element since we just mutate count it should be easy and it should return you have nothing in stack or your stack is cleared when stack is cleared . Note here stack empty and stack cleared is two different things
  • ADD some more function like 2nd last removed
  • a function which return last pop element whenever it called like

  const stack = [a,b,c,d,e,f,g,h]
  stack.pop() // removes h
  stack.pop() // removes g
  stack.pop() // removes f
  stack.pop() // removes e
  stack.pop() // removes d
  // our new function name could be anything you want for
  //instance reverter
  stack.reverter() // should return d
  stack.reverter() // now it  should return e
  stack.reverter() // now it  should return f
  stack.reverter() // now it  should return g
  stack.reverter() // lastly it  should return h
  stack.reverter() // lastly it  should return "no more removed items"
