Answer: Use the unshift() Method
You can use the unshift() method to easily add new elements or values at the beginning of an array in JavaScript. This method is a counterpart of the push() method, which adds the elements at the end of an array. However, both method returns the new length of the array

Insert an element after an element in an array?
To begin, obtain the element to be added, such as x Then, say pos, get the position where this element will be put. Then shift the array items one position ahead, then do the same for all the other elements next to pos. Because the location pos is now empty, insert the element x there.

What does it mean for a subscript to be out-of -bounds?
This is a type of error that usually occurs in computer programs. An array is defined in which the elements of the array are identified by one or more subscripts. Suppose you have an array which is declared to be of dimension 23. Then if the program tries to access element 26 in that array, it cannot because there is no element of the array in that position. That is when you will get this error message.
Write an algorithm to insert an item to a given location in sorted array?
To insert a number N into array A at index I: // Resize A if necessary If A is too small to add a new element then resize A // Right-shift all elements starting from position I For i = A.length to I A[i] = A[i - 1] // Insert new item A[I] = N
Why you need to sort an array?
Because in any type of search the element can be found at the last position of your array so time complexity of the program is increased..so if array when sorted easily finds the element within less time complexity than before..
Program in c to delete an element in sorted array?
You cannot delete elements from an array. But you can move the elements: if (del_index < no_of_elements-1) { memmove (&array [del_index], &array [del_index+1], sizeof (array [0]) * (no_of_elements - del_index - 1)); } --no_of_elements;

Write a program in c to find the largest no out of a matrix of order mn?
/* using ellipses (...) to indicate tabs for clarity */ double largest (double *array, int M, int N) { ... int i, j; ... double *element; ... double answer = array[0][0]; ... for (i=0; i<M; i++) { ... ... for (j=0; j<N; j++) { ... ... ... element = array + i*M + j; ... ... ... if (*element > answer) answer = *element; ... ... } ... } ... return answer; }
