Ans. Recursion
The simple idea that we use in this approach will be to check all the available paths. For this we create a recursive function let’s say MINIMUM_STOP_HELPER() that will return the desired path. The function will take fuel left, distance travelled, next gas station, and the array of all the stations as its parameters.
 
The base conditions for this recursive function will be:
 
• If you have enough fuel
• If y...read more

Here first, we append the number of words of ‘SECRET_INFORMATION’ and ‘!’ into our resultant decoding string ‘ENCODED_INFORMATION’. Then we append the length of each word and ‘!’. At last, we find the ‘ASCII’ value of each character and then add 3 into the ASCII value. Then we convert this ASCII value into a character and replace this with...read more

Ans. Optimal Solution
• Traverse the string and swap the first character with the last character, the second character with the second last character and so on.
• Basically, you need to swap the i-th character with the (N-i-1)-th character where N is the length of the string and 0-based indexing is considered.
