Nagarrow Interview Experience

I attended an interview at Nagarrow in Oct 2019. I face coding round .they taken system round. In the system round, there was three-question as below.

• Print second-highest number from given array.
  Method like : Public int secoundhighest(int inpute1, int[] input2)
• Get string coding and decoding length from the input string.
  Method like: Public Int return coding(string input)
  Example:

  input: "ABC";
  Output: 123;
  
  input: "12345";
  Output: ABCDE;

• Find HCF and LCM possibility length pairs from any single number
  Example:

  If you pass 4 its output should be like
  {0, 1}, {1, 0}, {1, 1}, {1, 2}, {2, 1}, {2, 3}, {1, 4}
  Find out length of pairs.
