You are given the array-like data structure Listy, which does not have a size. method. It does, however, provide an elementAt I function that returns the element at index I in the array of elements.  0( 1) time. If I exceeds the data structure's boundaries, it returns -1. (As a result, the data  structure only works with positive numbers.) Given a Listy of sorted positive integer , Determine the index at which an element x appears. If x happens more than once, you may return any index.

Write the function lastOf which searches the array a for the last occurance of any value contained in the array b. Returns the index if found. If not found, return -1. arrays.cpp 1 #include 2 3 int lastof(const int a[), int alen, const int b[], int blen) 4 { int res = 0; for (int i = 0; i =0 ; j--) if (b[j] == a[i]) { if(res[1, 9, 4, 5, 1, 5, 1, 12, 8, 11, 2, 11, 7, 8] b1->[7, 5, 9] last0f(al, 14, b1, 3): -1 Expected: 12 al->[1, 9, 4, 5, 1, 5, 1, 12, 8, 11, 2, 11, 7, 8] b2->[7, 7] lastof (al, 14, b2, 2): -1 Expected: 12 a2->[3, 2, 1, 14, 10, 6, 13, 1ө, 11, 13, 14] b2->[7, 7] lastof (a2, 11, b2, 2): -1 Expected: -1 а2->[3, 2, 1, 14, 10, 6, 13, 1ө, 11, 13, 14] b1->[7, 5, 9] last0f (a2, 11, b1, 3): -1 Expected: -1 а2->[3, 2, 1, 14, 10, 6, 13, 10, 11, 13, 14] b3->[11, 2, 1, 15] lastof (a2, 11, b3, 4): -1 Expected: 8 Score 2/5

this is insturction Write a program which prompts the user to enter up to 15 floating point numbers (terminated with a non-numeric), reads them into an array, then prints the following. The program must use an array (not a vector) to get credit. The array values in the original order, separated by commas, with no trailing comma at the last value. The array values where the order of each adjacent pair of elements is swapped, separated by commas (NOT every element swapped with its next neighbor, which would just move the first element to the end, but every original pair swapped only in that pair. For an odd element count, the last element should not change. See examples below.) The smallest number in the array. Example program outputs with user input shown in bold font: Enter up to 15 numbers, and a non-numeric to quit: 1 0 -1.001 # Original array: 1, 0, -1.001 The swapped array: 0, 1, -1.001 Smallest number: -1.001 Enter up to 15 numbers, and a non-numeric to quit: 1 0 -1.001 5 ,…

An array is positive dominant if it contains strictly more unique positive values than unique negative values. Write a function that returns true if an array is positive dominant. Examples ispositiveDominant([1, 1, 1, 1, -3, -4]) // There is only 1 unique positive value (1). // There are 2 unique negative values (-3, -4). ispositiveDominant([5, 99, 832, -3, -4]) → true ispositiveDominant([5, 0]) → true ispositive Dominant([0, -4, -1]) → false
