You are given a string of length N. Your task is to reverse the string word by word. The input may contain multiple spaces between words and may have leading o...read more
Ans. Brute force
• Create a String ans to store the reversed string.
• Initialize a variable i to 0 and iterate the whole string through a while loop.
• Skip initial spaces by just incrementing i.
• Create a String that will store the current word.
• Add the currentword and space at the beginning of ans.
• After traversing the whole string, check if the length of ans is greater than 0 then return ans after removing the last space otherwise r...read more

Q3. 
Maximum Difference Problem Statement
Given an array ARR of N elements, your task is to find the maximum difference between any two elements in ARR.
If the maximum difference is even, print EVEN; if it is...read more
Ans. Find Max And Min
We will iterate over ARR and find the MAX and MIN of the ARR. And if the MAX - MIN is odd the return “ODD” else return "EVEN". 
The algorithm will be-
1. MAX = -1, MIN= 10 ^ 9 + 1
2. For VAL in ARR.
   1. If MAX < VAL
      1. MAX = VAL
   2. If MIN > VAL
      1. MIN = VAL
3. IF (MAX-MIN) % 2
   1. Return ODD
4. ELSE
   1. Return EVEN

Q4. 
Remainder When Divided By 11 Problem Statement
Determine the remainder when a given number, 'N' in the form of a string, is divided by 11.
Input:
The first line contains an integer 'T' denoting the numb...read more
Ans. Using Modulo Property
1. Since the number is very large we can not simply calculate N % 11.
2. Now, any number say 256 % 11 can be calculated as (25*10 + 6)%11. Which in turn can be calculated as (( 25*10)%11+ 6)%11 or ( (25%11)*10 + 6)%11. Similarly 25%11 can be calculated as (2*10+5)%11. Therefore , 256 %11 can be finally calculated as ( ( (2*10 + 5)%11 )*10 + 6)%11.
3. So, the idea is to store the number N in string Str.
4. Take a ...read more

Steps :
• Use a minValue variable to find the index of the minimum element of the array.
• Use a loop to iterate over all the elements of the array.
• Use a nested loop to find the minimum ele...read more
