WebIn this video we will be learning about reversing a string using stack. we will read each character of String and push each character to the stack. WebThat approach uses O (n) stack space. You could reduce this to O (log n), by splitting the string in half, reverse the last half, reverse the first half, add the two reversed halves together, and return the new string. Perhaps not as clear and straight forward as your solution, but not by that much. – AJNeufeld Mar 30, 2016 at 17:33 fmk2 connector
