We have a string, "Hello World", which we want to reverse: The String to Reverse txt ="Hello World"[::-1] print(txt) Create a slice that starts at the end of the string, and moves backwards. In this particular example, the slice statement[::-1]means start at the end of the st...
One of the common Java coding interview questions is towrite a program to reverse a String in place in Java, without using additional memory. You cannot use any library classes or methods likeStringBuilderto solve this problem. This restriction is placed becauseStringBuilderandStringBufferclass define...
