String Starts or Ends with given String
Given an array
stringsArray of strings, and startString, endString as inputs, write a JS program to filter the strings in stringsArray starting with startString or ending with endString.
Quick Tip
You can use the array method filter() and logical operator OR ( || ).
Input
- The first line of input contains a string stringsArray
- The second line of input contains a string startString
- The third line of input contains a number endString
Output
- The output should be a single line containing an array of filtered strings
Sample Input 1
['teacher', 'friend', 'cricket', 'farmer', 'rose', 'talent', 'trainer']
t
r
Sample Output 1
[ 'teacher', 'farmer', 'talent', 'trainer' ]
Sample Input 2
['dream', 'player', 'read', 'write', 'trend']
p
d
Sample Output 2
[ 'player', 'read', 'trend' ]
Polynomial
Given polynomial, write a program that prints polynomial in Cix^Pi + Ci-1x^Pi-1 + .... + C1x + C0 format.Input
The first line contains a single integer N.
Next N lines contain two integers Pi, Ci separated with space, where Pi denotes power and Ci denotes coefficient of Pi.Output
Print the polynomial in the format Cix^Pi + Ci-1x^Pi-1 + .... + C1x + C0, where Pi's are powers in decreasing order, Ci is coefficient, and C0 is constant. There will be space before and after the plus or minus sign.
If the coefficient is zero, then don't print the term.
If the term with the highest degree is negative, the term should represent -Cix^Pi.
For the term where power is 1, represent it as C1x instead of C1x^1.
If the polynomial degree is zero and the constant term is also zero, then print 0 to represent the polynomial.
For term Cix^Pi, if the coefficient of the term Ci is 1, print x^Pi instead of 1x^Pi.Explanation
If N = 4
For power 0, the coefficient is 5
For power 1, the coefficient is 0
For power 2, the coefficient is 10
For power 3, the coefficient is 6.
Then polynomial represents "6x^3 + 10x^2 + 5"Constraints
N <= 100
0 <= Pi < 1000
-1000 <= Ci <= 1000
Sample Input

Prefix Suffix
Write a program to check the overlapping of one string's suffix with the prefix of another string.Input
The first line of the input will contain a string A.
The second line of the input will contain a string B.Output
The output should contain overlapping word if present else print "No overlapping".Explanation
For example, if the given two strings, A and B, are "ramisgood" "goodforall"
The output should be "good" as good overlaps as a suffix of the first string and prefix of next.
Sample Input 1
ramisgood
goodforall
Sample Output 1
good
Sample Input 2
finally
restforall
Sample Output 2
No overlapping

Matrix Rotations
You are given a square matrix A of dimensions NxN. You need to apply the below given 3 operations on the matrix A.
Rotation: It is represented as R S where S is an integer in {90, 180, 270, 360, 450, ...} which denotes the number of degrees to rotate. You need to rotate the matrix A by angle S in the clockwise direction. The angle of rotation(S) will always be in multiples of 90 degrees.
Update: It is represented as U X Y Z. In initial matrix A (as given in input), you need to update the element at row index X and column index Y with value Z.
After the update, all the previous rotation operations have to be applied to the updated initial matrix.
Querying: It is represented as Q K L. You need to print the value at row index K and column index L of the matrix A. Input
The first line contains a single integer N.
Next N lines contain N space-separated integers Aij (i - index of the row, j - index of the column).
Next lines contain various operations on the array. Each operation on each line (Beginning either with R, U or Q).
-1 will represent the end of input.Output
For each Query operation print the element present at row index K and colum index L of the matrix in its current state.Explanation

For R 90, clockwise rotation by 90 degrees, the matrix will become
3 1
4 2
For Q 0 0, print the element at row index 0 and column index 0 of A, which is 3.
For Q 0 1, print the element at row index 0 and column index 1 of A, which is 1.
Again for R 90, clockwise rotation by 90 degrees, the matrix will become
4 3
2 1
For Q 0 0, print the element at row index 0 and column index 0 of A, which is 4.
For U 0 0 6, update the value at row index 0 and column index 1 in the initial matrix to 6. So the updated matrix will be,
6 2
3 4
After updating, we need to rotate the matrix by sum of all rotation angles applied till now(i.e. R 90 and R 90 => 90 + 90 => 180 degrees in clockwise direction).
After rotation the matrix will now become
4 3

Next for Q 1 1, print the element at row index 1 and column index 1 of A, which is 6.

Temperature Conversion
You are given the temperature T of an object in one of Celsius, Fahrenheit, and Kelvin scales.
Write a program to print T in all scales viz Celsius, Fahrenheit, and Kelvin.
Formula to convert from Fahrenheit F to Celsius C is C = (F - 32) * 5 / 9.
Formula to convert from Kelvin K to Celsius C is C = K - 273.
Here "C", "F", "K" represent that the temperature scale is in Celsius, Fahrenheit and Kelvin scales respectively.
The input contains the temperature (a number) and the unit of the temperature scale (C, F, K) without any space.
The output contains temperature in Celsius, Fahrenheit and Kelvin scales in each line in the format similar to input and the value of the temperature is rounded to 2 decimal places.Input
The first line of the input contain a temperature Value in one of Celsius, Fahrenheit, and Kelvin scales.Output
The first line of output should contain the Celsius value and the unit of the Celsius without any space.
The second line of output should contain the Fahrenheit value and the unit of the Fahrenheit without any space.
The third line of output should contain the Kelvin value and the unit of the Kelvin without any space.Explanation
For example, if the given temperature Value is 25C then Celsius value is 25.0C, Fahrenheit value is 77.0F, and Kelvin value is 298.0K.
