compare

问题 I want to compare a character in a string with the letter "R". So I want to check if the character on the position i in the string is a "R", a "L" or a "F". This is my code, but it doesn't word... I'm a Java beginner and really happy about every idea to improve my code and makes it work. for (int i = s.length()-2; i >= 0; i--){ if (s.charAt(i) == "R"){ s = s + "L";} else if (s.charAt(i) == L){ s = s + "R";} else {s = s + "F";} // s = s + s.charAt(i); }//for By the way, the complete exercise

问题 I don't know why the below happens, and I can't find source code relative. Can anybody explain to me? var s, ss struct{} // two empty structs arr1 := [6]*struct{}{&s} // array with empty struct pointer arr2 := [6]*struct{}{&ss} // array with empty struct pointer fmt.Println(&s == &ss, arr1 == arr2) // false, true var l, ll struct{A int}{} arr3 := [6]*struct{A int}{&l} // array with empty struct pointer arr4 := [6]*struct{A int}{&ll} // array with empty struct pointer fmt.Println(&l == &ll,

问题 I have two inputs that when I start typing number, it automatically changes to currency, like this: 1,000 10,000 100,000 1,000,000 so how do you compare these two inputs? Because it is a comma, it creates a comparative problem. function priceCompare() { var price_meterVal; var priceVal; $("#price_meter").on("keyup",function () { price_meterVal = $($("#price_meter")).val().replace(/,/g, ''); }); $("#price").on("keyup",function () { priceVal = $($("#price")).val().replace(/,/g, ''); }); if

问题 I have this problem: I want to iterate and compare each item of array1 against each item of array2, both arrays have the same lenght. When the value of both items coincide I store the value j in my indexOfInterest[] array for later use. This is the code that I use, works well but its extremely slow comparing large arrays (thousands of items), can anyone help me in implement an efficient algorithm for this task. int i,j; int counter = [array1 count]; int indexOfInterest[counter]; for (i = 0; i

问题 I'm trying to compare a Character from a Char-Array with a char in my assembly code. This is the C-Code I use to start the assembly code: char a[] = "abc"; char b = 'a'; int size = 3; int d = _asm_main(a); printf("Char a: %s\n",a); printf("Erg:%d\n",d); and this is the assembly code: _asm_main: push {r6,r7,r8,lr} mov r8,r0 ldr r7,[r8,#2] mov r6,r7 b compare compare: cmp r6,#'c' beq true b false true: mov r0,#1 b end false: mov r0,#2 b end end: pop {r6,r7,r8,pc} BX lr It works for 'c' but if I

问题 I want to compare characters iteratively and return mismatches between 2 columns of a data frame. It should not return if x2x, y67y, as x remains x and y remains as y. Input: x y x_val y_val A B x2x, y67h, d7j x2y, y67y, d7r B C x2y, y67y, d7r x2y, y67y, d7r C A x2y, y67y, d7r x2x, y67h, d7j C D x2y, y67y, d7r x67b, g72v, b8c D E x67b, g72v, b8c x67r, g72j I want to add a column val and return differences between x_val and y_val Output: x y x_val y_val val A B x2x, y67h, d7j x2y, y67y, d7r

问题 I want to use the standard sort function for sorting points in respect to their distance of another point (e.g. their barycenter). I know I can write a custom compare function, but I don't know how to pass a parameter to it. I want to have it thread-safe, so I do not want to store the parameter at one central location. Is there a way how to pass additional parameters to a custom compare function? // Here is a compare function without a parameter for sorting by the x-coordinate struct
