I have an array of 3 known elements.I know that 2 elements of them have the sum of 100 and I need to find the location of the two elements which have this sum ex. A[3] 5 25 75 the solution for this prob. is second & third location Thanks,

Hey all, So declaring integers successively in memory (using .word) in an array is all well and understandable. Since an integer is 4 bytes in length, as is a memory word. For example: .data x: .word 2, -13, 24, 123 #initialization of elements 0 to 3 of array x However, how would...

halfway through my code so its a bit of mess but this is simple what i need to do. I have a JLabel array of 6 labels. a random number is generated, its then split into its digits into a 6 element array of integers. now i need to update the Jlabels with the integer array of digits. my...
