Q1. How to calculate motor power for conveyor?
Ans. 
Motor power for conveyor can be calculated using the formula P = (T x V)/1000.
• Determine the total weight of the load and the length of the conveyor belt.

• Calculate the total resistance to motion, including frictional resistance and the force required to lift or lower the load.

• Determine the motor speed and calculate the torque required to drive the load.

• Use the formula P = (T x V)/1000 to calculate the motor power.

• Choose...read more

Q1. 
Anagram Substring Search
Given two strings 'STR' and 'PTR', identify all starting indices of 'PTR' anagram substrings in 'STR'. Two strings are anagrams if one can be rearranged to form the other.
Input:
...read more
Ans. 
Implement a function to find all starting indices of anagram substrings of a given string in another string.
• Create a frequency map of characters in the 'PTR' string.

• Use a sliding window approach to check for anagrams in 'STR'.

• Return the starting indices of anagram substrings found.

• Example: For input 'BACDGABCD' and 'ABCD', output should be [0, 5].

Q1. 
Print All Permutations of a String
Given an input string STR, generate and print all possible permutations of the string.
Input:
str
Output:
All permutations of the input string, each on a new line.
...read more
Ans. 
Generate and print all possible permutations of a given input string.
• Use recursion to generate all permutations by swapping characters in the string.

• Maintain a visited array to keep track of characters already used in a particular permutation.

• Print each permutation as it is generated.

• Handle duplicate characters by skipping swapping if the character is already in the current position.
