Que.1 Find the Smaller Angle

            
  var Minimal_Angle = (h, m) => 
  {
     // Calculate angle made by hour hand with respect to 12 o'clock
    let hourAngle = (h % 12) * 30 + m / 2;
    
    // Calculate angle made by minute hand with respect to 12 o'clock
    let minuteAngle = m * 6;
    
    // Calculate absolute difference between two angles
    let angleDiff = Math.abs(hourAngle - minuteAngle);
    
    // Take smaller angle between two possible angles
    let angle = Math.min(angleDiff, 360 - angleDiff);
    
    // Return minimal angle
    return angle;   
  };
 
        

Que.2 Check whether the year is Leap year or not.

             
  var Check_Leap = (year) => 
  {
   // Check if the year is divisible by 4
    if (year % 4 === 0) {
      // If the year is divisible by 100 and not divisible by 400, it is not a leap year
      if (year % 100 === 0 && year % 400 !== 0) {
        return "Non Leap Year";
      } else {
        // Otherwise, it is a leap year
        return "Leap Year";
      }
    } else {
      // If the year is not divisible by 4, it is not a leap year
      return "Non Leap Year";
    }
  };
        

Que.3 Perfect Number Check.

             
  var Perfect_Check = (N) => 
  {
    // Find the divisors of the number and add them
    let sum = 0;
    let M = 1;
     // loop through all divisors of the number
    while(N>=M) {
     if (N % M === 0) {
       sum += M;
      }
      M++;
    }
    // Check if the sum of divisors is equal to the input number
    if (sum === N) {
      return "YES";
    } else {
      return "NO";
    }
          
  };
 
        

Que.4 Reverse a Number.

             
  var Reverse_Number = (N) => 
  {
    // Initialize a variable to store the reversed number
    let reversedNumber = 0;
  
    // Loop through the digits of the number and reverse them
    while (N > 0) {
      let remainder = N % 10;
      reversedNumber = reversedNumber * 10 + remainder;
      N = Math.floor(N / 10);
    }
  
    // Return the reversed number
    return reversedNumber;
  
  };
        

Que.5 Substring Check.

  var Substring_Check = (S1, S2) => 
  {
    if (S1.includes(S2)) {
      return "YES";
    } else {
      return "NO";
    }   
  };
