Problem Statement You have given a String as an array of Characters, reverse the string by modifying the input array. Implement the problem in O(1) extra memory. Example Input :- ["h", "e", "l", "l", "o"] Output :- ["o", "l", "l", "e", "h"] Input :- ["m", "o", "r", "n", "i", "n", "g"] Output :- ["g", "n", "i", "n", "r", "o", "m"] Solution This problem can be solved in following steps :- • Create three variables firstpointing to index 0, secondpointing to last index (n-1, where n is the length of an array) and temp. • Copy the character at firstvariable to temp, the character at secondvariable to firstand character at tempvariable to second. • Move the firstvariable to right and secondvariable to left. • Repeat steps 2 and 3, until first is less than second.
