- 1Code a JavaScript callback function for the Array.map method to ('Yu Yamaguchi') evaluate an array of integersidentify the integers that are Prime numbersreturn the Prime numbers in the new array 2 Code a JavaScript callback function for the Array.reduce method to evaluate an array of integersdetermine the smalles integerreturn the smalles integer Note: if there are identical integers, the function is to return the last one.Write the method sum2D() which accepts a two dimensional integer array and returns the sum of all the elements of the array.Instrument shellsort to print the number of compares divided by the array sizefor each increment. Write a test client that tests the hypothesis that this number is asmall constant, by sorting arrays of random Double values, using array sizes that areincreasing powers of 10, starting at 100
- Write a method reverse that takes an array as an argument and returns a new array with the elements in reversed order. Do not modify the array. Only edit code in the /* Your code code goes here */ portions.Write a method SortTheEvens(), that first shifts all the even numbers of an input array to the left side in that array and then sorts all even numbers in that array.Note: You are not allowed to use direct indexing and can only use ptr++ and ptr-- operators. i.e. *(ptr + i) and ptr[i] are not allowed.Do using c++ programming language.Write the method printTail() method that accepts an array of integers and an integer index as parameters and prints all the array elements starting from the index passed. For example if printTail(x,5) is invoked, it should print all the elements of the array x starting at x[5].
- 5. Write a static method largestColumnFirst() that receives as parameter a 2D array numAr,finds the column with the largest sum, and switches it with the first column. For example:6 7 9 4 8 9 7 6 4 83 2 7 4 1 → 7 2 3 4 19 4 5 8 3 5 4 9 8 3Write method findZero, as started below. findZero should return the index of the first element of array A that contains the value zero, starting from position 0 up through position pos. If no element of A from position 0 to position pos contains the value zero, then findZero should return –1. For example:(in java) Array (A) Position (pos) Value returned by findZero(A, pos) 1 0 2 5 6 0 -1 1 0 2 5 6 1 1 1 0 2 5 6 2 1 1 0 2 0 6 2 1 1 0 2 0 6 4 1 1 2 3 4 5 4 -1 Complete method findZero below. Assume that it is called only with values that satisfy its assumptions as stated below. // Description: Returns smallest index k // such that (0 <= k <= pos) and (A[k] == 0) // Assumptions: 0 <= pos < A.length public int findZero(int[] A, int pos) {Write in java code Create an array myArr of 10 integer elements and initialize/fill it with numbers (not sorted) between 0 and 20; for example myArr = [ 12, 3, 19, 5, 7, 11,….etc.]. (a) print the array. (b) Use method sort() of class Arrays to sort myArr and print it after sorting. (c) Use the arraycopy() method of class System to copy myArr to another array called my2ndArr, then print both arrays. (d) use method equals() of class Arrays between the two arrays and print the results. (e) use method fill() to fill my2ndArr with 99 in all elements and then use method equals()and print the result whether the two arrays are equal or not. (f) use the method binarySearch() to search myArr for the value 15 and print the result
- DO NOT POST EXISTING ONE: Write a java method called SearchKey that return the indices of the first and the last occurences of an element k in an array.The function should Return [-1,1] in case the element was not foundWrite method findZero, as started below. findZero should return the index of the first element of array A that contains the value zero, starting from position 0 up through position pos. If no element of A from position 0 to position pos contains the value zero, then findZero should return –1. For example: Array (A) Position (pos) Value returned by findZero(A, pos) 1 0 2 5 6 0 -1 1 0 2 5 6 1 1 1 0 2 5 6 2 1 1 0 2 0 6 2 1 1 0 2 0 6 4 1 1 2 3 4 5 4 -1 Complete method findZero below.
