ProblemWe are required to write a JavaScript function that takes in an array of numbers. Our function should return a string made of four parts −a four character 'word', made up of the characters derived from the first two and last two numbers in the array. order should be as read left to right (first, second, second last, last), the same as above, post sorting the array into ascending order, the same as above, post sorting the array into descending order, the same as above, post converting the array into ASCII characters and sorting alphabetically.The four parts should form a ...

ProblemWe are required to write a JavaScript function that takes in a string of English alphabets. Our function should construct a new string and every consonant should be pushed forward 9 places through the alphabet. If they pass 'z', start again at 'a'. And every vowel should be pushed by 5 places.ExampleFollowing is the code − Live Democonst str = 'sample string'; const moveWords = (str = '') => { str = str.toLowerCase(); const legend = 'abcdefghijklmnopqrstuvwxyz'; const isVowel = char => 'aeiou'.includes(char); const isAlpha = char => legend.includes(char); let res = ''; for(let i ...

ProblemWe are required to write a JavaScript function that takes in a string. Our function should convert the string according to following rules −The words should be Caps, Every word should end with '!!!!', Any letter 'a' or 'A' should become '@', Any other vowel should become '*'.ExampleFollowing is the code − Live Democonst str = 'ban censored words'; const maskWords = (str = '') => { let arr=str.split(' '); const res=[] for (let i=0; i
ProblemWe are required to write a JavaScript function that takes in a string of some mathematical operation and return its literal wording.ExampleFollowing is the code −const str = '5 - 8'; const convertToWords = (str = '') => { const o = { "+" : "Plus", "-" : "Minus", "*" : "Times", "/" : "Divided By", "**" : "To The Power Of", "=" : "Equals", "!=" : "Does Not Equal", } const n = { ...

When it is required to find the closest pair to the Kth index element in a tuple, the ‘enumerate’ method can be used along with ‘abs’ method.Below is the demonstration of the same −Example Live Demomy_list = [(5, 6), (66, 76), (21, 35), (90, 8), (9, 0)] print("The list is : ") print(my_list) my_tuple = (17, 23) print("The tuple is ") print(my_tuple) K = 2 print("The value of K has been initialized to ") print(K) min_diff, my_result = 999999999, None for idx, val in enumerate(my_list): diff = abs(my_tuple[K - 1] - val[K - 1]) if diff ...

When it is required to create a list from a given list that have a number and its cube, the list comprehension can be used.Below is the demonstration of the same −Example Live Demomy_list = [32, 54, 47, 89] print("The list is ") print(my_list) my_result = [(val, pow(val, 3)) for val in my_list] print("The result is ") print(my_result)OutputThe list is [32, 54, 47, 89] The result is [(32, 32768), (54, 157464), (47, 103823), (89, 704969)]ExplanationA list is defined, and is displayed on the console.The list comprehension is used to iterate through the list, and use the ‘pow’ method to get ...

When it is required to find the maximum and minimum K elements in a tuple, the ‘sorted’ method is used to sort the elements, and enumerate over them, and get the first and last elements.Below is the demonstration of the same −Example Live Demomy_tuple = (7, 25, 36, 9, 6, 8) print("The tuple is : ") print(my_tuple) K = 2 print("The value of K has been initialized to ") print(K) my_result = [] my_tuple = list(my_tuple) temp = sorted(my_tuple) for idx, val in enumerate(temp): if idx < K or idx >= len(temp) - K: ...

When it is required to find the size of a tuple, the ‘sizeof’ method can be used.Below is the demonstration of the same −Example Live Demoimport sys tuple_1 = ("A", 1, "B", 2, "C", 3) tuple_2 = ("Java", "Lee", "Code", "Mark", "John") tuple_3 = ((1, "Bill"), ( 2, "Ant"), (3, "Fox"), (4, "Cheetah")) print("The first tuple is :") print(tuple_1) print("The second tuple is :") print(tuple_2) print("The third tuple is :") print(tuple_3) print("Size of first tuple is : " + str(sys.getsizeof(tuple_1)) + " bytes") print("Size of second tuple is : " + str(sys.getsizeof(tuple_2)) + " bytes") print("Size of third tuple is: ...

ProblemWe are required to write a JavaScript function that takes in two strings. The first string specifies the user name and second the owner name.If the user and owner are the same our function should return ‘hello master’, otherwise our function should return ‘hello’ appended with the name of that user.ExampleFollowing is the code − Live Democonst name = 'arnav'; const owner = 'vijay'; function greet (name, owner) { if (name === owner){ return 'Hello master'; } return `Hello ${name}`; }; console.log(greet(name, owner));OutputHello arnav
ProblemWe are required to write a JavaScript function that takes in an array of numbers of length at least three.Our function should simply return the third smallest number from the array.ExampleFollowing is the code − Live Democonst arr = [6, 7, 3, 8, 2, 9, 4, 5]; const thirdSmallest = () => { const copy = arr.slice(); for(let i = 0; i < 2; i++){ const minIndex = copy.indexOf(Math.min(...copy)); copy.splice(minIndex, 1); }; return Math.min(...copy); }; console.log(thirdSmallest(arr));Output4
